Dornier Seastar CD2

The Dornier Seastar is an all-composite twin-turboprop amphibious flying boat originally designed by Claude Dornier Jr. in the early 1980s as a modern successor to Dornier's long lineage of flying boats (Wal, Do 24, Do 26). It features a distinctive parasol wing with two Pratt & Whitney Canada PT6A-135A turboprops mounted in a single over-wing nacelle in push-pull (in-line) configuration — an arrangement that eliminates asymmetric thrust on engine failure, a critical safety advantage for an amphibian operating from confined water.

The prototype first flew on 17 August 1984 from Hamburg, with a second prototype flying in April 1987 from Oberpfaffenhofen. European and American type certificates were awarded in 1990–1991, but the original program stalled after only three aircraft were built as Dornier's parent company wound down general aviation activities. The type languished through the 1990s and 2000s under a succession of partnership attempts.

In November 2018, Chinese investors (Wuxi Industrial Development Group) committed approximately €150 million to Dornier Seawings GmbH to restart production of an updated variant, the CD2, featuring modernized avionics (Garmin G1000 NXi), updated PT6A-135A engines, five-bladed MT composite propellers, and systems revisions. The CD2 first flew on 28 March 2020. First customer deliveries were repeatedly delayed and are currently targeted for 2026, with aircraft under production at both the original Oberpfaffenhofen facility in Germany and a sister assembly line in Wuxi, China. Total production remains in single digits. The Seastar occupies a niche similar to the Grumman Grumman G-73 Mallard — a luxury/utility amphibian for VIP transport, island hopping, resort operations, and SAR — but brings turbine reliability and composite corrosion immunity that no legacy amphibian can match.

Two findings from the FAA's own type certificate that a serious US buyer needs to see before anything else on this page. First, the FAA-validated certificate for this airplane (A62EU, Revision 4, 2007) states in its Import Requirements section: "This aircraft is not eligible for operations in the United States." No serial range or configuration qualifier is attached to that sentence anywhere on the sheet. A US type certificate exists, and it says the airplane cannot currently be operated here under it — buyers should confirm the present import status directly with the FAA Small Airplane Directorate (Kansas City) or Dornier Seawings before assuming otherwise. Second, that same certificate's Revision 4 dates to 2007 and its holder of record is "Dornier Seastar GmbH & Co KG" — the ORIGINAL, pre-restart company — and it still certificates the original 4-blade McCauley propellers, not the 5-blade MT composite propellers press coverage attributes to the 2018-restart CD2. Whether the modernized configuration has its own FAA approval was not established this session; see Regulatory Status below.

This section is honestly incomplete, and that is the correct state for this page rather than an oversight. A type certificate publishes no performance data at all, and no Pilot's Operating Handbook or AFM for the CD2 is publicly reachable — Dornier Seawings' own website returned a TLS handshake failure on every attempt this session, and this is a pre-delivery, single-digit-production aircraft with no independent flight-test press coverage of the kind larger types get. Cruise speed, fuel burn, range, rate of climb, service ceiling and all four runway distances are therefore left out of the frontmatter rather than carried forward from the prior, uncited generation pass. See raw/press/press-dornier-seastar-avweb-2026-09-12.md for exactly what was searched.

What the certificate DOES establish: the airplane is certificated in commuter category, with a VMO (Max Operating Speed) of 180 KCAS rather than a classic Vne — meaning the certificate's speed limits scale differently from every Normal-category piston single elsewhere in this catalogue. VA is 140 KCAS, VS1 (flaps up, at MTOW) is 78 KCAS, and VS0 (flaps 40°, at MTOW) is 65 KCAS. The certificate separately states a Max. Diving Speed (VD) of 227 KCAS — a structural design limit for gust/flutter margin, not a speed the airplane is meant to be flown to; earlier versions of this page conflated the two.

One design feature worth recording even without hard numbers: the push-pull inline twin arrangement — both PT6A-135A engines on the aircraft centerline, one pulling and one pushing — eliminates the asymmetric yaw of a conventional wing-mounted twin on an engine failure, which several press accounts describe as enabling long single-engine cruise legs for range extension. No independently-published single-engine endurance figure was found to back a specific number, so none is stated here.

This section cannot be computed honestly with what is currently sourced, and is left qualitative rather than backfilled with removed numbers. Useful load requires a basic empty weight, and no basic empty weight is published anywhere reachable this session — the certificate gives only a "Min. Design Weight" (2,900 kg / 6,339 lb), which is a structural/CG certification floor, not a weight-and-balance figure, and the prior page's 6,393 lb empty weight appears to have been that same figure mislabeled (see raw/tcds cert passage). Range is likewise unsourced (see Performance Notes).

What can be said without a number: at 458 gallons usable (3,058 lb of fuel) against a 10,141 lb MTOW and a 12-seat cabin, this is a large-fuel-fraction airplane by the standards of this catalogue, and the general turbine-amphibian pattern — full fuel and full seats are mutually exclusive, with the realistic executive mission trading passenger count for range — almost certainly holds here too. A specific useful-load figure and a real payload-range table should be added once a manufacturer weight-and-balance document or a verified empty weight is located; until then, stating one would repeat the exact error this pass corrected.

The aircraft is best understood as a medium-range luxury/utility amphibian whose mission sweet spot is 200–550 nm legs between water-accessible destinations, not a long-distance cross-country machine.

• Business travel (8): Excellent for VIP point-to-point between water-accessible resorts, islands, and coastal estates; pressurization is NOT provided, limiting altitudes but fine for its typical mission profile. 12-seat capacity and large cabin make it viable for executive shuttle roles. See Business Travel.
• Cargo hauling (7): Large rear loading door handles meaningful freight to remote water-accessible sites. Ideal for island resupply, SAR equipment transport. (Useful load is not stated on this page — see validator_exempt on empty_weight_lbs — so this score is qualitative, based on cabin volume and door size rather than a number.) See Cargo Hauling.
• Backcountry / bush (6): Water-capable for remote lakes and protected coastal waters, but the 10,000+ lb airframe and turbine economics put it far outside owner-flown bush operations. Scored for commercial/charter bush utility only. See Backcountry / Bush Flying.
• Surveying (7): Twin turbine reliability, long single-engine endurance, and amphibious flexibility make it suitable for maritime patrol, coastal surveying, and SAR missions — and Dornier's own "Orca" mission derivative (see Variants) targets exactly this role.
• Cross-country (6): Unpressurized operation and a certificate that gives no confirmed service ceiling or range limit this to regional missions rather than continental crossings; scored qualitatively pending a real performance source.
• Training/aerobatics/local fun (1–2): Completely unsuitable — not a personal aircraft.

CD2 standard panel is Garmin G1000 NXi with dual 10-inch PFDs and large MFD, GFC 700 autopilot, synthetic vision, dual GTN-class navigators, ADS-B in/out, and optional TCAS II. Marine-specific additions include water-mode gear logic and configurable water rudder controls. Customer options include Gogo/Iridium connectivity, cabin management systems, and weather radar. No avionics retrofit market exists — all aircraft delivered from Dornier Seawings come with an effectively identical forward-fit panel. See Avionics Pricing Reference for G1000 NXi reference pricing, though in Part 23 turbine installations the panel is an integrated factory fit.

As a newly-restarted production aircraft with fewer than 10 total airframes ever built across both the original and CD2 programs, there is essentially no STC aftermarket. All modifications are factory options:

• Interior configurations: VIP 6-seat, commuter 10–12 seat, combi, medevac, SAR (with observer windows and searchlight provisions)
• Floats/hull options: N/A — hull is integral composite
• Cargo door / belly pod: Factory option for utility operators
• Searchlight / FLIR mast: SAR/patrol option

Owner-initiated modifications are impractical given certification complexity and the tiny fleet.

This is the Seastar's largest practical weakness outside its acquisition cost. The global fleet is too small to support a meaningful independent MRO network; virtually all heavy maintenance routes back to Dornier Seawings facilities in Oberpfaffenhofen (Germany) or Wuxi (China), with a limited authorized service partner program being developed.

• Parts availability: Poor — airframe parts come from the factory on order. Composite repairs require factory-trained technicians. PT6A engine support is universal through Pratt & Whitney Canada's worldwide network, which partially offsets airframe scarcity.
• Mechanic familiarity: Rare — only factory-trained A&Ps handle the airframe. PT6A turbine mechanics are common.
• Annual direct operating cost: Roughly $550k–$800k/year at 300 hours annual utilization, driven by dual turbine reserves (~$250/hr/engine), fuel ($350/hr), insurance ($80k+), hangar, and maintenance reserves. Marketing claims that operating cost is "one-third of an equivalent helicopter" are broadly credible when compared against a twin-turbine medium helicopter in the same payload class.
• Expensive items: PT6A hot sections, composite hull inspections, landing gear overhaul, props.

No price is stated on this page, and that is a finding rather than an omission. The prior generation pass carried a $7.2M-$9.5M band with no source of any kind. This session searched for a replacement and found none: the restarted CD2 has not yet delivered a customer aircraft as of this catalogue's research date, so there is no used market to observe, and Dornier Seawings' own site — where a current list price would be published — is unreachable (TLS failure on every attempt). The only price mentioned anywhere reachable is "about $6 million," a pre-2018-restart figure describing a different corporate configuration under the original ownership, before the ~$170M Chinese-funded relaunch and roughly a decade of inflation; it is not carried forward. See raw/market/market-dornier-seastar-search-2026-09-12.md. This is a pre-delivery, single-digit-production, newly-relaunched aircraft, and the honest state of its pricing is that a buyer would need a direct factory quote — treat this as a real catalogue gap, not a settled $0. Key valuation drivers once real pricing exists:

• Time since new / hours: Turbine time on wing is the dominant factor; a low-time aircraft near new is worth near list; an aircraft approaching hot-section or overhaul loses $300k–$750k per engine pending shop visit.
• Hull condition: Saltwater vs freshwater history is a major discount driver; freshwater-only aircraft command significant premiums.
• Interior configuration: VIP completions carry $500k–$1.5M premiums over utility interiors but may not recoup on resale.
• Certification coverage: Aircraft with both EASA and FAA certifications maintained command broader buyer pools. See Aircraft Valuation Methodology.

With fewer than 10 airframes total and CD2 only recently certified, there is no meaningful AD history. Known watch-items from the original prototypes and analogous composite amphibians include:

• Composite hull delamination in chronically wet stowage areas — the major operational advantage over riveted aluminum amphibians, but not zero-maintenance; requires periodic NDT inspection of the hull-to-deck joint.
• Landing gear corrosion: Saltwater exposure degrades retractable gear components; freshwater rinse after every saltwater operation is mandatory.
• PT6A-135A hot section inspection at 1,800 hours, overhaul at 3,600 hours — standard Pratt practice.
• Propeller erosion from spray ingestion — the push prop in particular is vulnerable; MT composite props have replaceable leading edge tape.
• Water rudder linkage wear from repeated extension cycles.

Prospective buyers should expect to rely exclusively on Dornier Seawings and their authorized service network for most maintenance actions.

The Seastar falls in the turbine amphibian insurance category, which is among the most restrictive in general aviation. Underwriters view amphibians as high-hull-loss-frequency risks (water operations, gear-up-on-water accidents are the #1 amphibian loss driver), and the Seastar's composite hull and rarity make repair estimates unpredictable. Expect:

• Hull insurance: Roughly 1.0%–1.5% of hull value annually for professional crews with significant amphibian time — no dollar figure is given here because no sourced hull value exists on this page (see Valuation Factors); the stored typical_hull_insurance_annual_usd ($85,000) is carried over from the prior generated pass and not independently verified this session.
• Liability: $10M smooth limits are standard for charter/commercial operations.
• Pilot requirements: ATP with multi-engine turbine PIC time and amphibian rating; most underwriters require factory-led initial training plus recurrent every 6 months and a second type-rated pilot for most commercial ops.
• Operational restrictions: Wave-height limits, approved water bodies, and crew-rest endorsements are common policy conditions.
