Incident: B737, G-OBMD, Dublin Airport, 18 Jan 1997: Report No 1998-002

February 20, 1998

SYNOPSIS

As G-OBMD commenced passenger disembarkation at Stand 33 the ground maintenance engineer said that he noticed smoke coming from the point where the ground power lead connects to the aircraft.  This was followed by a number of flashes (of flame).  He immediately went to alert the aircraft Captain and staff.  Cabin Crew No. 1 used her own initiative and ordered an evacuation as she understood that it was a serious fire.  In addition to using the forward exit onto the airbridge some passengers exited via the overwing emergency doors and down the chute at the rear passenger door also.  The evacuation was completed quickly and without incident.

The ground power lead at Stand 33, which is fixed in a ground power pit, was removed for examination.  It was found that one of the two fixing bolts connected through the ground power plug had shorted across 2 phases (A & B phases), apparently as a result of damage caused by a vehicle driving over the plug while it lay on the ramp.

This is not an uncommon occurrence.

The short caused severe arcing in the plug when it was connected to the aircraft and switched on.  It was this occurrence that was witnessed by the ground maintenance engineer.

 

 

Accident: HS 748-2A, G-AYIM, Dublin Airport, 6 July 1996: Report No 1998-001

February 13, 1998

SYNOPSIS

The accident was notified to the Air Accident Investigation Unit (AAIU) by Dublin Air Traffic Control at 0110 hours on the 6 July 1996. An AAIU Inspector arrived on scene at 0200 hours on the same day.
 
The aircraft, which was on a scheduled cargo flight from Liverpool, landed on Runway 28 at Dublin Airport at 0100 hours and taxied to Stand 55 on the South Apron. Having brought the aircraft to a stop, the cockpit crew commenced their shutdown drills, which included a 30 second temperature stabilisation with engines at idling speed. During this time the marshaller approached from in front of the aircraft and chocked the nose wheel. Having chocked this wheel, a witness observed the marshaller walking backwards in an arc, giving a thumbs-up to the cockpit as he did so. Seconds later, the marshaller came in contact with the idling port propeller and received fatal injuries to his head. None of the witnesses present observed the actual propeller strike to the marshaller.

Accident: DC3, EI-ACF, Near Birmingham, 1 Jan 1953.

January 1, 1997

Department of Industry and Commerce Report (1953):

Formal Investigation into Causes and Circumstances of Accident, which occurred on 1st January 1953 to the DC-3 Aircraft EI-ACF.

Preamble and Report, Non -Statutory Inquiry (2002):

Accident involving a DC3 aircraft EI-ACF, the St. Kieran, near Birmingham on 1 January 1953 conducted by Mr. Patrick Keane, S.C. in March 2002.

Accident to Agusta Bell 206B 111 Registration EI-BMP near Headford, Co. Galway on July 29 1982.

January 25, 1983
Synopsis:
 
The accident occurred during an early morning charter flight from Ballynahinch castle to Shannon Airport. The pilot and the four passengers were killed instantly when the helicopter struck the ground some distance North of the direct overland route. Radiation fog was widespread in the area.
 
When the accident occurred the helicopter was being manoeuvred at low altitude in conditions of varying and restricted visibility.
No pre-crash defects were found in the helicopter and the accident probably occurred when the pilot lost adequate visual references and permitted the helicopter to strike the ground because of induced false sensations arising from spatial disorientation.
The probable cause of the accident was the pilots attempt to continue flight in deteriorating visibility. Reasons or contributory factors were not determined. There may have been some anxiety to complete the flight. Also important were the changing visual conditions actually experienced by the pilot.
 

Accident to Viscount 803 aircraft EI-AOF near Ashbourne, Co. Meath on 22nd June, 1967

June 14, 1968
Synopsis:
 
A training flight for the purpose of conversion of Aer Lingus cadet pilots to Viscount aircraft departed Dublin Airport 0644 G.M.T., 22 June 1967, with I.F.R. clearance from Air Traffic Control for training flight in the sector north-west of Dublin  Airport.  The pilot-instructor said his intention was to spend two hours in this sector and then to practise circuits and landings at the airport for one hour.
 
The aircraft climbed to its assigned flight level and obtained two revised clearances, for higher levels, from A.T.C. at 0656 and 0707 G.M.T. Its last transmission to A.T.C. was an acknowledgement of the last clearance, at 0708  G.M.T.
 
At 0743  G.M.T.  a telephone call from Ashbourne post office informed A.T.C. that  an aeroplane had crashed two miles north  of Ashbourne. Immediate radio-telephone calls were made to EI-AOF, without  response; and  full  emergency procedures  were initiated. Another Viscount training flight practising circuits at the airport was despatched at 0746 G.M.T. to make a search. The pilot sighted the wreckage of EI-AOF  at 0751  and information  on its  position  was  given to the airport  Fire Service.
Eye-witnesses stated  that EI-AOF  had hit the ground in a nearly-vertical attitude after diving from comparatively level flight at a low altitude and that violent fire and several explosions followed impact.
The three occupants-a  training  captain  and two cadet pilots-were killed at impact.
