PIPER PA-32-301 SARATOGA N8152Z(cn32-8006004)
Sutton Aicraft Salvage ,Palmer.Alaska.*On Thursday 14 July 2005 at Karluk, Alaska during the landing roll of the 14 CFR Part 135 air taxi passenger flight, a deer ran onto the runway, and was struck by the right horizontal stabilizer of the airplane. The right horizontal stabilizer and empennage were structurally damaged.
Probable Cause: A collision with a deer on the runway during the landing roll, which resulted in substantial damage to the tail of the airplane.*************On Friday 12 August 2011 Kodiak, Alaska the pilot and the operator's director of maintenance (DOM) were on a postmaintenance check flight. According to the pilot, while approaching to land, the throttle control became inoperative, resulting in a partial loss of engine power. The pilot selected a tidal beach as a forced landing site but was unable to reach it and landed in shallow water short of the site. The airplane sustained substantial damage to the wings and fuselage. The DOM reported that, while troubleshooting a recurring complaint of low engine manifold pressure, he noticed that the castellated nut, which connects the throttle linkage to the fuel control servo, was loose. He said that he removed the cotter pin, tightened the nut, and reinstalled the cotter pin. A postaccident engine examination revealed that a self-locking nut was missing from the throttle linkage arm, resulting in the disconnection of the throttle cable. The DOM said that the missing locknut was not the same one that he tightened but was a nut on the other end of the throttle linkage arm, about 2 inches from the castellated nut that he tightened. The DOM noted that he should have checked the security of the self-locking nut, but he did not. The self-locking nut was not recovered.
Probable Cause: A partial loss of engine power while on approach to land due to a disconnected throttle control linkage, and the maintenance director's inadequate inspection of the throttle linkage during maintenance.
