Event Details
On August 8, 2016, at 1508 Pacific daylight time, a Cessna TR182, registration N756FZ, experienced a right main landing gear collapse after landing at Zamperini Field Airport (TOA) in Torrance, California. The airplane was registered to M and S 182 LLC and operated by Pacific Skies Aviation under 14 Code of Federal Regulations Part 91. The local instructional flight, with a certified flight instructor and a commercial pilot undergoing instruction (PUI) on board, had departed TOA about 1338. Visual meteorological conditions prevailed, and no flight plan had been filed.
The flight instructor reported demonstrating a normal landing to the PUI. On approach, he extended the landing gear and configured the airplane for a normal landing. Landing checks were called out, and a green light verified that the landing gear was extended. The flare and initial touchdown were normal. Shortly after touchdown, the airplane listed to the right and entered a 180° skidding turn before coming to a stop. Neither occupant was injured.
Witness Observations
Two witnesses located at the airport reported seeing the airplane on final approach with its right main landing gear not fully extended.
Post-Accident Examination
A Federal Aviation Administration inspector from the Long Beach Flight Standards District Office arrived on site and observed the airplane on the runway with the nose and left main landing gear down and locked; the right main landing gear was fully retracted. During recovery, the airplane was lifted, and the right main landing gear freely fell into trail. A mechanic then manually placed the right side gear in the down and locked position. The airplane was lowered onto the landing gear and subsequently towed to a secured location.
During a post-accident examination, the airplane was placed on jacks for a gear swing test. The landing gear was cycled multiple times with no anomalies noted. The landing gear indicator lights inside the cockpit illuminated during the landing gear extension.
