NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FAA: CONDUCT, BY 4/30/95, FLIGHT TESTS TO DETERMINE THE EFFECTS OF TUNDRA (OVERSIZED) TIRES AND WHEELS ON THE PIPER AIRCRAFT CORPORATION PA-18 AIRPLANE'S FLIGHT CHARACTERISTICS--INCLUDING CRUISE, CLIMB, TAKEOFF, LANDING PERFORMANCE, AND IN BOTH STRAIGHT AND TURNING FLIGHT, STALL WARNING AND AIRCRAFT STABILITY AT OR NEAR THE CRITICAL ANGLE OF ATTACK. TAKE APPROPRIATE CORRECTIVE ACTION, EXPAND TESTING TO OTHER AIRPLANE TYPES EQUIPPED WITH OVERSIZED TIRES AS NECESSARY, AND DISSEMINATE THE TEST RESULTS TO THE AVIATION COMMUNITY.
In plain language (FlightFinder summary)
The FAA is asked to perform flight tests on Piper PA-18 airplanes fitted with oversized tires to understand how these modifications affect handling, performance, and stability. These tests should cover various flight conditions, including takeoff, landing, climbing, cruising, and stalls. Based on the findings, the agency must take necessary corrective steps, extend similar evaluations to other aircraft types with oversized tires if needed, and share the results with the aviation community.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
