LSFM's Boeing PT-13D Stearman
The Lone Star Flight Museum (LSFM)
is the owner and operator of this Boeing PT-13D Stearman
(S/N 42-109078), which is available for airshows, flybys,
film and warbird rides at airshows within Texas.
The Boeing Stearman was manufactured as an initial
training aeroplane by Boeing Aircraft Company (Witchita
Division), which eventually constructed at least 8500
Stearmans, or more than 10,300 if one includes spare
parts. No other biplane was ever built in this quantity.
Beginning in 1934, the Americans sold the Stearman for
export as the 'Kaydet.'
The Stearmans manufactured for the U.S. Army Air
Corps were the PT-13; PT-13A; PT-13B;
PT-17; PT-18; PT-27 and PT-13D. The U.S. Navy airplanes
were the N2S-1;-2;-3;-4 and-5. The
primary difference between the Army and Navy airplanes,
other than engines installed, was the tail wheel. Army
airplanes had a fully steerable tail wheel while the
Navy airplanes were equipped with a full swivel type
with a lock. Most Stearmans today have subsequently been
modified with the steerable tail wheel. The final
version of the Stearman was the E75, designated
PT-13D/N2S-5. It was the only complete standardization
of an Army and Navy production design during WWII and
was totally the same for both services.
Generally, all the Stearman airframes built are the
same with the only major difference being the engine
installed. Original engines included the Lycoming R-680
(225 hp); Continental R-670 (220 hp) and the Jacobs
R-755 (225 hp). Post-war modifications include the
Lycoming R-680 (300 hp); Pratt & Whitney R-985 (450 hp)
and the Jacobs R-775 (275 hp). The propellers generally
in use on Stearmans are the Sensenich wooden prop; the
ground adjustable McCauley steel blade prop and the
fixed pitch Hamilton Standard propeller.
Post-war civil requirements for surplus military
Stearmans is covered by Aircraft Specification A-743.
This document lists all the approved equipment allowed
on a standard category Stearman and the items that must
have been removed, replaced or modified when the
military surplus Stearman was first licensed as a
civilian airplane. Over the years there have been many
models and STC’s for the Stearman Series. The Stearman
makes an outstanding and fun civilian aircraft.
