Accident
On 21 June 2014, at 1515 UTC, a Beech F33A, registration N999F, experienced a landing gear failure while landing at Jersey Airport. The aircraft was on a private flight with two crew and one passenger on board. No injuries were sustained by any occupants.
History of the Flight
The pilot was inbound to Jersey Airport and was unable to obtain a green light indication for the left landing gear, despite several checks and attempts to recycle the gear. The pilot made an approach knowing that the left gear leg might not be locked down. After touchdown, the left gear leg slowly collapsed, causing the aircraft to veer off the runway onto the grass.
Damage
The left wing and landing gear sustained damage.
Landing Gear System
The F33A Bonanza landing gear actuation system consists of a central gearbox that drives three gear extension rods, one for each gear leg. The extension rod for the left gear leg was found to have failed in compression.
Previous Occurrences
This aircraft had experienced a gear leg collapse on landing in 2006. In November 2012, the extension rod for the left gear leg was found bent during the annual inspection and was replaced. It was this replacement rod that failed in compression at Jersey.
Cause
The cause of the failure to the extension rod was not determined. As a precaution, the central gearbox was being replaced.
