Beechcraft Model C90A King Air
Damaged Main Gear Actuator

Aircraft experienced a right main landing gear unsafe indication on gear extension at destination. After following emergency procedures, the crew was not able to obtain a safe indication. The aircraft landed and, on coming to a stop, the right main gear collapsed. Significant damage to the right main landing gear actuator support structure was discovered. The actuator was observed in the extended position.

Cirrus SR20
Cracked Nosegear Weld

Cracks discovered adjacent to weld on nose landing gear. Referencing service bulletin SB2X-32-22R1, this is a chronic problem discovered on a fleet of SR20s (T-53) operated by the USAF. Out of 24 aircraft, 22 were discovered with cracks.

Piper PA-24-250 Comanche 250
Failed Gear Transmission Mount

Pilot did not receive green down-and-locked light. Tower reported the gear appeared down. On landing, the gear collapsed; when the aircraft was lifted during recovery, the gear transmission and gear fell down and locked into place. Once the airplane was on jacks, it was found the gear transmission and motor assembly was pulled through the bulkhead, p/n 20601-06, at FS 87, and broke the channel assembly and bulkhead.

Piper PA-32RT-300T Turbo Saratoga SP
Broken Right Main Gear

The right main landing gear broke into two pieces after the aircraft made a normal landing on a dry runway. The airplane had no history of hard landings that might have stressed the gear and it was not overweight. The main body of the trunnion broke apart approximately half way down the body and the oleo rod also broke in half on the landing roll out. The gear departed the aircraft and slid approximately 20 yards.

Piper PA-46-350P Malibu Mirage
Damaged Nose Gear Actuator

The aircraft landed with nose wheel steering horn assembly jammed in engine mount tube, causing aircraft to depart runway. Impact with snow bank caused further nose gear collapse and overload failure of the nose gear actuator/engine mount interface. Suspect aircraft mishandling during ground towing may have caused sufficient damage to engine mount interface to reduce gear rake angle below 90 degrees (Reference maintenance manual 32-20-00 page 8, sheet 1 of 2, Fig. 3), which reduced clearance between wheel steering horn and engine mount tube. Gear extension coinciding with left rudder input is also suspected to have caused interference.
