Description

The accident followed an uneventful flight of returning holiday-makers, from Lanzarote, Spain, to Shannon, with the landing carried out on runway 24. Weather conditions in the approach and landing area showed rain, strong winds and associated turbulence.ÿOn landing, the aircraft’s nose wheel assembly collapsed rearwards.ÿ The aircraft continued along most of the length of runway 24 on its nose, finally coming to a halt beyond taxiway Alpha. An evacuation was carried out. CAUSAL FACTORS: “The accident was due to an excessive control column forward input, causing negative pitch attitude which led to a very high impact loading on the nose undercarriage, leading to the severing of the two nose wheels and the collapse of the nose gear strut assembly rearwards.ÿThis followed a chain of events, which contributed to the accident including the wind gusts, turbulence, the use of the autothrottle and the decision to land from an unstabilized final approach.”

Primary Cause

Excessive control column forward input caused negative pitch attitude, leading to high impact loading on the nose undercarriage, resulting in nose wheel assembly collapse and nose gear strut assembly severing.Excessive control column forward input caused negative pitch attitude, leading to high impact loading on the nose undercarriage, resulting in nose wheel assembly collapse and nose gear strut assembly severing.
