Narrative:A Piper PA-34-220T, G-ZZOT made abnormal runway contact during a landing gear-up go-around at Liverpool Airport, 15 August 2023.
The aircraft’s propellers struck the runway during a go-around from a simulated one engine inoperative (OEI) approach at Liverpool Airport that was inadvertently flown with the landing gear up. The serious incident occurred on a training flight being undertaken as part of a multi-engine instrument rating course
While the aircraft was fitted with an unsafe landing gear position warning system, the instructor had disabled it by pulling its circuit breaker (CB) due to nuisance warnings after a previous approach and go-around. His intention was to re-enable the warning system when downwind to land but cited distraction as a contributory factor for him omitting to reset the CB and not positively confirming the gear was down for the landing.
=AAIB Conclusion=
The aircraft’s propellers struck the runway after an inadvertent landing gear-up approach. While the aircraft was fitted with an unsafe landing gear warning system, the instructor had disabled it by pulling its CB during a go-around because the warning horn was causing intra-cockpit communication difficulties. His intention was to re-enable the warning system when downwind to land, but he cited distraction as a contributory cause for him omitting to reset the CB and not positively confirming the gear was down for the landing.
Had the warning system not been inhibited, it would have been more likely that the unintentional gear-up approach would have been detected and prevented by one or both of the pilots. The operator intended issuing formal guidance to its pilots that CBs should only be pulled if specifically required when following an approved abnormal procedure checklist
=Damage sustained to airframe=
Per the AAIB Report the damage sustained was Impact damage to both propellers and shock loading to both engines and propeller drivetrains. Minor damage to under surface of fuselage"
