N432CP

On June 1, 2022, about 1527 eastern daylight time, a Cirrus SR22, N432CP, was substantially damaged when it was involved in an accident near Wings Field Airport (LOM), Philadelphia, Pennsylvania. The private pilot and passenger received minor injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

The pilot reported he departed from Georgetown Regional Airport (GGE), Georgetown, South Carolina on an instrument flight plan to LOM. The climb and en route cruise portions of the flight were uneventful. During the approach to LOM, the pilot requested the RNAV6 approach. Clearance was granted to proceed to Modena (MXE) VOR at 3,000 ft, then he was cleared for the approach to LOM. The pilot began a normal approach on autopilot, and upon reaching the final approach fix, started the descent. The pilot reported that he reduced power during the final descent, and as he attempted to increase power, the engine did not respond to throttle commands. He said that the engine was still running, but when he moved the throttle forward, the engine rpm did not increase and that the throttle lever felt “loose.” The airplane did not have enough power to make it to LOM, and the pilot decided to make a controlled, off-airport landing. The pilot subsequently performed a forced landing to a golf course. After touchdown, the airplane collided with trees at the edge of a grassy area.

Postaccident examination of the airplane by a Federal Aviation Administration inspector revealed the airplane sustained structural damage to the left wing and forward fuselage, and that the empennage was partially detached. An examination of the engine confirmed valvetrain continuity throughout the engine. No abnormalities were noted with the airplane’s ignition system. The oil system exhibited a broken turbocharger oil supply line that appeared to be impact-related as oil spillage was observed directly under the broken line. Both the upper and lower engine cowlings were inspected with no additional indication of oil leakage.

During the inspection, the throttle lever was removed and examined in detail, with no defects were noted. The throttle lever was then reinstalled. Throttle and mixture continuity checks were performed; however, both cables had sustained impact damage and were broken away from the engine. The throttle lever at the throttle body was slightly loose on the throttle shaft, which allowed the lever to slip with observed “ratcheting.” The throttle lever attaching nut (which featured a single-use integral locking mechanism) was loose and needed to be tightened approximately 1/8-turn to fully engage.

The left wing displayed damage consistent with tree impact during the landing, and the area surrounding the wing root was damp and smelled of fuel. The left wing fuel tank contained about 1 to 2 pints of residual fuel, and about 1 pint of fuel leaked from the left wing root area during the recovery from the accident site. The right fuel tank had about 20 gallons of fuel. The fuel samples taken from both fuel tanks showed no indication of water or contamination. The fuel selector was found in the left tank position, with no fuel found in the fuel lines or fuel distributor. Residual fuel was found in the fuel line between the fuel manifold and the throttle body.

A flight control continuity check found continuity in the elevators and rudder. Both outer aileron quadrants were bent forward, separating the spherical bearing from the aileron drive pin on each side, which prevented a continuity check of the aileron system.

The airplane’s most recent annual inspection was completed on October 5, 2021, at an airframe total time of 1,293 hours (about 37 flight hours before the accident). The engine maintenance log entry for the inspection noted, in part, “Inspected and lubricated all engine controls.” No inspections or maintenance of the airplane’s engine controls were noted after that date.
