The Piper PA-11 Cub Special is a small aircraft produced by the US manufacturer Piper Aircraft . It is the successor to the Piper J-3 .
construction
The Piper J-11 is a two-seater shoulder- wing aircraft with tandem seats . The airframe was taken over from the J-3 almost unchanged, with the position of the engine slightly lowered and the windshield a little flatter. The cowling is like the Piper J-5 completely closed. The fuel tank was relocated to the left wing root. Both seats have been moved back a little. Early PA-11s were powered by a Continental A65 -8. Later, a Continental C90 -8 was optionally available as an engine.
The paint of the first PA-11 consisted of a metallic blue for the lower half of the fuselage and the “Lock Haven Yellow” for the remaining surfaces. Later copies were painted completely yellow with a brown decorative stripe.
With a total weight of 1,220 lb (553 kg ) and an average curb weight of 750 lb (340 kg), the PA-11 is light enough to perform well and heavy enough to be easier to fly than in stronger winds the lighter J-3. The PA-11 is suitable for short taxi distances during take-off and landing , but still has an acceptable cruising speed.

Modifications
The PA-11 was one of the first aircraft to be used for experiments with a nose wheel landing gear . Although the original design was based on a tail wheel landing gear , a conversion kit for a nose wheel landing gear was developed.
The nose wheel is connected to the rear engine mountings via V-shaped steel tubes. Control cables run directly from attachment points on the rudder pedals under the fuselage to the nosewheel standpipe, allowing the aircraft to be steered with the rudder pedals on the ground. The shock absorber consists of six circumferential rubber bands between the immersion pipe and the standpipe. For proper balance, the main landing gear was rotated one hundred and eighty degrees, which shifted the center of gravity further forward. The pilot sits in the front seat for additional stability. Most of the PA-11s still in operation today, however, are equipped with a tail wheel landing gear.
Some PA-11s have been fitted with floats .
The PA-11 also forms the basis of the Piper PA-18 .

Incidents
- On July 28, 1984, the pilot of the PA-11 with the registration number N80AH went into a too steep climb after a low flight maneuver at an altitude of approximately 300 feet AGL near Willows , California . This resulted in a stall due to the flight speed being too low . The machine then tipped forward and fell almost vertically to the ground. The 31-year-old pilot and his passenger died in the crash.
- On April 27, 1987, the PA-11 with the registration number N5093H crashed into a fish pond near Hollandale , Mississippi, during a low-level flight maneuver . The 30-year-old pilot was killed and his passenger was seriously injured. During the autopsy of the pilot, an alcohol content of 0.8 per mille and marijuana were found in the blood.
- On November 28, 1987, the owner of the PA-11 with the registration number N4767H was on a biennial check flight together with a flight instructor . In the course of the flight, the two flew to a sand runway near San Marcos , California . On approach for landing , the aircraft hit a rock, crashed and remained at the northeast end of the runway. The 43-year-old pilot and his flight instructor were killed in the accident and the aircraft was completely destroyed.
- On December 30, 1997, the PA-11 with the registration number N5532H crashed for unknown reasons near White Hills , Arizona . The 54-year-old pilot was killed in the crash.
- On May 8, 1999, the PA-11 with the registration number N4582M took off from Lander , Wyoming . On the way to coyotes hunting the aircraft crashed a near landline from over open ranch land. The machine was destroyed and both occupants were killed. The overhead line showed no signs of contact by the aircraft. The NTSB suspects that the pilot attempted a sudden maneuver to avoid the overhead line due to inattention. In doing so, he presumably lost control of the aircraft.
- On June 16, 2019, the PA-11 with the registration number N209H took off from Columbia Airport in Columbia , California with the destination Modesto . In the vicinity of Copperpolis, the plane collided with a power line northeast of Lake Tulloch and then crashed into the lake. The pilot was fatally injured.
