Accident:Piper PA34-200 Seneca II,G-EZYU,Galway Airport,16 Feb 2008:2008-009

May 29, 2008


  

SYNOPSIS

 


While dealing with a perceived technical problem about 20 minutes flying time from Galway Airport, the Pilot became unsure of his position and requested a radar heading to Galway from Shannon Air Traffic Control (ATC). On arrival at Galway the Pilot carried out a landing on Runway (RWY) 08, where the aircraft was observed by ATC to “porpoise” or bounce a number of times, before departing the runway near it’s end, onto an open grass area. While the aircraft was substantially damaged, the Pilot and passenger were unhurt. The Airport Fire Services later towed the aircraft to the light aircraft apron.


Serious Incident: Robinson R44, EI-TOY, UCD Belfield, 23 Sept 2007: Report No 2008-008

May 23, 2008

 SYNOPSIS

The helicopter had just taken off on a short flight. The engine started to run rough and lose power. As the helicopter was over a large open area, but surrounded by a built-up area, the pilot lowered the collective pitch lever and initiated an autorotation. During the autorotation descent the engine stopped completely. The pilot successfully performed a power-off autorotation and landed the helicopter without damage. The Investigation found that carburettor icing was the probable cause of the event.

Incident: Hughes H369HS, N239MW, Athlone, Co.Westmeath, 07 Jul 2007: Report No 2008-007

May 9, 2008




  SYNOPSIS

 


The single engine helicopter landed on the upper floor of a multi-story car park in the centre of Athlone town.  A Car Park Attendant claimed he had attempted to wave the aircraft away as it did not have permission to land.  The Attendant stated, as the helicopter continued to land, he then took refuge behind a door where he was injured by the helicopter’s main rotor downwash.


 


The landing, at an elevated site in the centre of a large town, by the single engine helicopter was contrary to the Rules of the Air. 




Serious Incident: EHI Merlin HC Mk 3, ZJ137, Salthill, Co Galway, 24 June 2007: Report No 2008-006

April 11, 2008

  SYNOPSIS

On departure from the static display park at the Salthill Airshow 2007, an emergency egress hatch separated from the right-hand side cargo sliding door of a Merlin helicopter and fell to earth. The Investigation found that the locking mechanism of the egress hatch had been interfered with by an unknown member of the viewing public during the course of the day. This unlocked condition, remained undetected during the pre-flight inspection by the aircrew. Two spectators reported receiving minor injuries.

Serious Incident: B737-8AS/MD-83, EI-DCZ/OE-IKB, Reporting Point BANBA, 23 September 2007: Report No 2008-004

March 5, 2008

SYNOPSIS

Two passenger aircraft entered Irish controlled airspace near Reporting Point BANBA at high level off the South East coast of Ireland. One was an MD-83 routing northwards towards Dublin from Faro, and the second was a B737 routing westwards towards Cork from Stansted.  The former was maintaining Flight Level (FL) 280, while the latter, which was cruising at FL300, was cleared initially by the Shannon based Air Traffic Control (ATC) Radar Controller to descend to FL290 and subsequently to FL100. This ATC clearance conflicted with the path of the northern bound aircraft, and, in spite of at least four warnings, one verbal and three electronic, the Radar Controller appeared not to comprehend the closing speeds of the two aircraft and allowed the higher one to descend and lose the required minimum vertical and lateral separation from the other. What ensued was a critical failure of the human element of the ATC system to rectify this situation.
 
The last resort safety net in this extreme circumstance, each aircraft’s on board Traffic Alert and Collision Avoidance System (TCAS), automatically activated with a commanded warning to each aircraft. The pilot of each aircraft reacted correctly to this TCAS warning, one climbed his aircraft as instructed by the system and the other descended his aircraft as instructed by the system. A potential mid-air collision was thus narrowly avoided due to the TCAS activation and the correct response of the pilots. With separation subsequently re-established by ATC, both aircraft continued onwards and landed at their respective destinations.
 
The Air Accident Investigation Unit (AAIU) of the Department of Transport was notified of this Serious Incident shortly after it occurred. Three Safety Recommendations are made as a result of this Investigation.

SYNOPSIS


 


The aircraft departed a private airfield on a local flight and proceeded in a northerly direction at an altitude of approximately 1,000 ft.  After approximately 20 minutes flying time the engine stopped without warning.  The pilot, the sole occupant of the aircraft, was unable to restart the engine in the time available.  In the subsequent forced landing the aircraft impacted heavily with the ground and was severely damaged.  The pilot suffered serious injuries.
