Cessna 172B Skyhawk (1961)

The 1961 Cessna 172B introduced two changes that shaped the 172's identity for the next six decades. First, the "Skyhawk" name debuted as a deluxe option package -- full exterior paint, deluxe interior, full panel with avionics -- effectively the upmarket trim level. Second, usable fuel rose to 39 gallons from the 172A's 37 -- same two 21-gallon tanks, a smaller unusable allowance. (The often-repeated 50 lb gross-weight increase to 2,250 lbs is not this airplane: TCDS 3A12 Rev. 88 gives the 172A and the 172B the same 2,200 lbs, and 2,250 lbs arrives with the 172C in 1962. What the 172B does gain is a wider aft C.G. envelope at weight -- 1,850 lbs against the 172A's 1,733.) The engine also stepped to the Continental O-300-D with longer engine mounts (3 inches forward, balancing CG) and a reshaped cowling with a pointed spinner.

About 988 172B examples were produced in 1961. The 172B is the first 172 most pilots would recognize as a "modern" 172 in profile: swept tail, pointed spinner, longer nose. Only the fastback fuselage (rear windows didn't wrap around until the 172D in 1963) still hints at the airplane's 1950s origins.

Distinguishing Features (vs 172A and 172C)

The "Skyhawk" Distinction

In 1961, "172" and "Skyhawk" were not synonymous -- "Skyhawk" was the deluxe option package adding paint, full interior trim, dual nav radios, and other upgrades on top of the base 172B airframe. Today, when shopping a 1961 model, "172B Skyhawk" and "172B" refer to the same airframe; the Skyhawk-trim cars simply had nicer original equipment. After decades of avionics and interior upgrades, the original Skyhawk vs base distinction is mostly irrelevant for resale.

The name became universally applied to all 172s by the late 1960s and is now the de facto product name regardless of trim level.

114 KTAS cruise at 75% power, 7.0 GPH. Climb rate of 645 FPM at sea level (max gross 2,200 lbs, per TCDS 3A12 Rev. 88). With a typical 1,280 lb empty weight, useful load is ~920 lbs. Four 180-lb adults = 720 lbs, leaving 200 lbs for fuel and baggage -- about 33 gallons, short of the 39 usable the airplane carries. Full fuel (39 gal usable = 234 lbs) leaves 686 lbs for people and baggage: three adults and a light bag, not four adults.

Real-world cruise: 105-108 KTAS at economy settings, ~6.0 GPH. Range with reserves: 495 NM at economy settings.

The O-300-D is the most-produced O-300 variant and the easiest to support. Parts availability is "good" compared to the O-300-A/C which are rarer. Field overhaul cost: $39,500–$50,500. Many owners considering an overhaul evaluate the Lycoming O-320 conversion STCs as an alternative.

Pricing tracks 172A closely. 172Bs with original "Skyhawk"-trim paint and interior in restored condition can command a small collector premium ($3,000-$5,000) over base-trim 172Bs in equivalent condition.

Universal Cessna 172 pre-buy concerns apply. 172B-specific:

1. Pull starter: The 172B retained the pull starter from the 172/172A. Verify the starter handle, cable, and engagement linkage are in good condition. Key starter conversion STCs exist.
2. Reshaped cowling fit: The 172B's revised cowling is unique to this variant; aftermarket replacement cowlings may not fit perfectly. Original cowling availability is fair.
3. CG envelope shift: The longer engine mounts moved CG slightly forward. Verify weight-and-balance documentation reflects current configuration, especially if engine has been changed.
4. Original Skyhawk-trim paint: Original 1961 paint is unlikely to remain; check for paint quality, prep, and corrosion underneath any repaint.
