Cessna 150 Model Information

Production was 122 in 1958, 648 in 1959 and 354 in 1960. [7]

150A

The 1961 model incorporated enough changes to justify a suffix letter and thus was designated the 150A.

The A had its main landing gear moved aft by two inches to eliminate the problem of the aircraft ending up on its tail while loading people and baggage and also to improve nose wheel steering authority.

Cessna 150G on floats

The A also had 15 larger rear side windows and new adjustable seats. 344 were constructed. [7]

150B

The 150B was the 1962 model . It had a new propeller that increased cruise speed by 2 knots (3.7 km/h) and the option of a two-passenger child seat for the baggage compartment. 331 B models were built. [7] The Commuter version cost USD$8,995. [8]

150C

The 1963 model was the C, which introduced the option of larger 6.00X6 inch tires to replace the standard 5.00X5 tires and fuel quick drains. 472 were completed. [7]

150D

The 1964 D model brought the first dramatic change to the 150 - the introduction of a rear window under the marketing name Omni-Vision. The rear window changed the look of the 150 and cost 3 mph (4.8 km/h) in cruise speed. It also resulted in a larger baggage compartment and a greater structural weight allowance for baggage from 80 to 120 lb (54 kg). The square tail fin from previous years was retained for another two years. Elevator and rudder mass balances were increased to reduce flutter potential caused by the less aerodynamic rear fuselage. The gross weight of the aircraft was also increased in 1964 to 1,600 lb (730 kg), where it would stay until the advent of the Cessna 152 . 804 150Ds were built. [7]

Many people find the new cabin more "airy" and pleasant, due to the increased light. [9]

150E

The 1965 Cessna 150E saw only the addition of new seats, although the standard empty weight went up 40 lb (18 kg) that year to 1,010 lb (460 kg). The E model saw production increase to 1637 aircraft. [7]

150F

The 1966 model saw great changes to the 150 design. The fin was swept back 35 degrees to match the styling of the Cessna 172 and other models. The cabin doors were made 23 wider, new brakes were brought in and the 6.00X6 tires were made standard. The previously manual flaps were now electrically actuated through a panel-mounted flap switch. The old electric stall warning system was replaced with a pneumatic-type. The baggage compartment was enlarged by 50. A total of 3087 of the newly styled F models were produced. [7]

1966 was also the first production of French Reims-built F-150s, with 67 built as the F150F. [10] .

150G

In the 1967 model, the instrument panel was redesigned. The doors were bowed out to give three more inches of shoulder and hip room which was needed in the small cabin. The G model also saw a new short-stroke nose oleo introduced to reduce the drag created by the nose wheel assembly. The previously fitted generator was replaced by a 60 amp alternator, reflecting the increasing avionics that the planes were being fitted with.

The G model was also the first Cessna 150 variant certified for floats. A total of 2114 G models were built, plus 152 built by Reims as F150G. [7]

150H

The 1968 model 150 was designated the H. It introduced a new-style center console, designed to improve legroom. A new electric flap switch was also fitted that allowed hands-off retraction of the flaps, but not extension. 2007 150Hs were built in Wichita, with 170 built by Reims as the F150H. [7]

150I

There was no 150 India model as Cessna didn't want it to look like a Cessna 1,501. This didn't stop Cessna from designating an India model Cessna 172 however. [7]

150J
The 150J brought a new key-operated starter that replaced the old pull-style starter. The new starter was more car-like but not as reliable as the old one and more expensive to repair, too.
An auxiliary power plug was made available as an option in 1969, too, along with rocker style electrical switches. 1714 J models were built, plus 140 built by Reims as the F150J.

150K
1970 was the year that Cessna introduced the A150K Aerobat, a Cessna 150 with limited aerobatic capabilities. It retained the 100 horsepower (75 kW) Continental O-200 all 150s used, but the Aerobat had more structural strength. It was rated for +6/-3 g and sported four-point harnesses, skylights, and jetisonable doors, along with checkerboard paint schemes and removable seat cushions so parachutes could be worn. In 1970, an Aerobat cost $12,000 as opposed to the $11,450 for a standard 150. [11]
Both the new Aerobat and the non-aerobatic 150K also sported new conical cambered wingtips in 1970. A total of 832 K models were built, including A150Ks.Reims built 129 as the F150K and 81 as the A150K .

150L
The 150L had the longest production run of any 150 sub-model, being produced 1971-74.
New in 1971 was tubular landing gear legs with a 16 greater width (6 feet 6 inches(1.98 m) to 7 feet 7 inches (2.31 m) for better ground handling. These replaced the previous flat steel leaf spring gear. Also in 1971, the landing and taxi lights were moved from the wing leading edge to the nose bowl to better illuminate the ground. They were an improvement, but bulb life was reduced due to the heat and vibration of that location. They moved back to the wing on the 1984 model Cessna 152.
The L also introduced a longer dorsal strake that reached to the rear window. This was done more for styling than for aerodynamics and the empty weight accordingly went up 10 lb (4.5 kg) over the K. 879 were built in 1971.

In 1972 the L received new fuel filler caps to reduce moisture seepage, and better seats and seat tracks. 1100 were built in 1972.

The 1973 L model brought in lower seats to provide more headroom for taller pilots. 1460 of the 1973 models were built.

The final L model was produced in 1974. The only changes this model year were the propeller on the A150L Aerobat, to a new Clark Y airfoil that increased cruise by 4 mph (6.4 km/h). 1080 150s were produced in 1974. [7]

Total L production was 4519, plus the 485 built by Reims as the F150La and 39 FA150L Aerobats.

150M
The final Cessna 150 model was the 150M. It introduced the Commuter II upgrade package that included many optional avionics and trim items as standard. The M also brought an increased fin height, by 6 inches (150 mm). This increased the rudder and fin area by 15 to improve crosswind handling. The M was produced for three years: 1975-77.

Inertia reel restraints became available as an option with the 1975 model year. 1269 1975 model 150Ms were built.

In 1976 the M gained a suite of electrical circuit breakers to replace the previous fuses used. It also was fitted with a fully-articulated pilot seat as standard equipment. 1399 were constructed.

The 1977 model year was the last for the Cessna 150. It added only pre-select flaps, allowing the pilot to set the flaps to any setting and then leave the aircraft to move the flaps to that position, without the pilot holding the switch. Only 427 1977 model 150Ms were built as production shifted to the improved Cessna 152 in the early part of 1977.

The many refinements incorporated into the 150 over the years had cost the aircraft a lot of useful load. The very first 150 weighed 962 lb (436 kg) empty, whereas the last M Commuter II had an empty weight of 1,129 lb (512 kg). This increase in empty weight of 167 lb (76 kg) was offset only by a gross weight increase of 100 lb (45 kg) in 1964. [4] The 152 would bring a much-needed 70 lb (32 kg) increase in gross weight to 1,670 lb (760 kg).

A total of 3097 M models were built during its three-year run. [7] An additional 285 were built by Reims as the F150M and 141 FA150M Aerobats with the Rolls Royce Continental 0-240-A engine. Reims also built 75 A150Ls with F150M modifications.
