皇冠体育app

Summary:

皇冠体育app accident was reported to the AAIB by Air Traffic Control following the emergency landing of the aircraft at Birmingham International Airport. 皇冠体育app investigation was conducted by:

Mr P T Claiden (Investigator-in-Charge)
Ms G M Dean, Mr R W Shimmons (Operations)
Mr J R McMillan, Mr M P Jarvis (Engineering)
Mr P Wivell (Flight Recorders)

On a scheduled cargo flight from Li猫ge Airport to London Stansted Airport the crew diverted to Nottingham East Midlands Airport due to unexpectedly poor weather conditions at Stansted. 皇冠体育app weather conditions at EMA required a CAT IIIA approach and landing. On approach, at approximately 500 feet agl, the crew were passed a message by ATC advising them of a company request to divert to Liverpool Airport. 皇冠体育app commander inadvertently disconnected both autopilots whilst attempting to reply to ATC. He then attempted to re-engage the autopilot in order to continue the approach.

皇冠体育app aircraft diverged to the left of the runway centreline and developed a high rate of descent. 皇冠体育app commander commenced a go-around but was too late to prevent the aircraft contacting the grass some 90 m to the left of the runway centreline. 皇冠体育app aircraft became airborne again but, during contact with the ground, the right main landing gear had broken off.

皇冠体育app crew subsequently made an emergency landing at Birmingham Airport (BHX).

Commonly known as East Midlands Airport, and referred to as EMA in this report.

皇冠体育app investigation determined the following:

Causal factors:

1. ATC inappropriately transmitted a company R/T message when the aircraft was at a late stage of a CAT III automatic approach.

2. 皇冠体育app commander inadvertently disconnected the autopilots in attempting to respond to the R/T message.

3. 皇冠体育app crew did not make a decision to go-around when it was required after the disconnection of both autopilots below 500 ft during a CAT III approach.

4. 皇冠体育app commander lost situational awareness in the latter stages of the approach, following his inadvertent disconnection of the autopilots.

5. 皇冠体育app co-pilot did not call 鈥榞o-around鈥� until after the aircraft had contacted the ground.

Contributory factors:

1. 皇冠体育app weather forecast gave no indication that mist and fog might occur.

2. 皇冠体育app commander re-engaged one of the autopilots during a CAT III approach, following the inadvertent disconnection of both autopilots at 400 ft aal.

3. 皇冠体育app training of the co-pilot was ineffective in respect of his understanding that he could call for a go-around during an approach.

One Safety Recommendation is made.
