Serious Incident: two Boeing 737 8AS aircraft, EI-EFF and EI-DHA, Dublin Airport, on 8 March 2015: Report 2015-022
December 24, 2015
SYNOPSIS
On the evening of 8 March 2015, the Air Movements Controller (AMC) at Dublin Airport (EIDW) reported a loss of separation between a departing and a landing aircraft.
The departing aircraft (EI-EFF, using ‘callsign 342’) was cleared for take-off with a landing aircraft (EI-DHA, using ‘callsign 45TR’) at 3.2 NM on final approach to the same runway. Re-appraising the situation, the AMC attempted to stop the departing aircraft at the holding point, however, as a result of a blocked transmission the departing aircraft continued past the stop line which was in accordance with its previously issued clearance. Clearing the departing aircraft for an immediate take-off, the departing aircraft became airborne prior to the arriving aircraft touching down.
A runway occupation alert, a function of the Advanced Surface Movements Guidance and Control System (A-SMGCS), activated as a result of the reduced separation between the aircraft during the event.
SERIOUS INCIDENT: Robinson R44 Raven II, EI-DDA, Ringaskiddy, Co. Cork, 18 August 2014: Report 2015-021
December 16, 2015
SYNOPSIS
The helicopter was on a training flight from Cork Airport. During the en route phase, in the vicinity of Ringaskiddy, Co. Cork, the Pilot felt vibration accompanied by low rotor Revolutions Per Minute (RPM) warnings. The Pilot broadcast a “Mayday” transmission to ATC and made a successful autorotation(5) into an agricultural field. There were no injuries. The Investigation found that the helicopter’s engine suffered a gross mechanical failure and the engine sustained substantial damage during the event.
(5) Autorotation: A procedure in which a helicopter rotor is driven solely by the relative motion of air acting on its rotor blades as the helicopter descends without engine power.
ACCIDENT: Cessna 208B, registration N208B, Ballyart Co. Limerick, 13 December 2014: Report 2015-020
November 12, 2015
SYNOPSIS
The aircraft was departing from Brittas House Airfield in Co. Limerick on a private flight to a destination in the United Kingdom. With normal take-off power applied and the aircraft well established in the take-off run, the Pilot felt that the aircraft was not accelerating as expected. Despite the application of extra power the speed did not increase sufficiently for the take-off to be continued safely. The Pilot attempted to overfly the deep ditch at the departure end of the runway but made contact with fencing posts in the process. The aircraft came to rest at the far boundary hedge of the adjacent field and sustained substantial damage. The Pilot exited the aircraft without injury.
ACCIDENT: Boeing 737-8AS, EI-EMH and EI-EKK LINK 2, Dublin Airport, 7 October 2014: Report 2015-019
October 9, 2015
SYNOPSIS
While turning right from Taxiway (TWY) F2 via LINK 2 and taxiing towards TWY A to hold short of runway (RWY) 34 at EIDW, the tip of the port side winglet of EI-EMH struck the starboard side elevator of EI-EKK. At the time, EI-EKK was stationary on LINK 2 at the entrance to TWY F1 awaiting sequenced departure off RWY 28. The winglet of EI-EMH and the elevator of EI-EKK were substantially damaged. There were no injuries.
Three Safety Recommendations have been made as a result of this investigation.
ACCIDENT: Piper, PA-32R-301, N808CA Ballyboe, Co. Tipperary 31 May 2015: Report 2015-018
October 8, 2015
SYNOPSIS
The aircraft was landing at Ballyboe Airfield near Clonmel following a flight conducted under Visual Flight Rules (VFR) from Newmarket Heath Airfield in the United Kingdom. During the landing roll the left wingtip of the aircraft contacted high crops adjacent to the grass runway. This contact caused the aircraft to veer to the left side of the runway. The aircraft departed the prepared surface and the right-hand undercarriage leg collapsed resulting in further damage to the aircraft. The aircraft came to rest straddling the edge of the runway and the adjacent field. There were no injuries.
ACCIDENT: Cessna TU206G Stationair 6, G-SKYE Near Abbeyshrule, Co. Longford, 21 June 2014: Report 2015-017
September 21, 2015
SYNOPSIS
The aircraft, a Cessna TU206G, was being used for parachuting/skydiving activities at Abbeyshrule (EIAB) on the day of the accident. Shortly after take-off, the Pilot felt what was described as a “knock” following which the engine lost power. This resulted in the Pilot making a forced landing in a nearby field. There were five people on board the aircraft – the Pilot and four skydivers. The skydivers comprised of two tandem pairs, with each pair being made up of a qualified skydiver and a person skydiving for charity secured to him. Following the forced landing, all occupants successfully evacuated the aircraft, which sustained substantial damage.
The Pilot and qualified skydivers reported no injuries at the scene. The two charity skydivers attended a local hospital, but were released a short time later. The Investigation found that the cause of the engine power loss was a failure of the crankshaft.
Five Safety Recommendations are issued as a result of this investigation.
INCIDENT: BAE Systems Avro 146-RJ85, EI-RJH, Near Dublin Airport, 22 May 2014: Report 2015-016
August 26, 2015
SYNOPSIS
Shortly after departure from Dublin Airport (EIDW), the Flight Crew noticed fumes and smoke entering the cockpit. Fumes and smoke were also reported in the passenger cabin. The Flight Crew donned their oxygen masks and smoke goggles and carried out the appropriate emergency checklist actions. The aircraft returned to EIDW and landed safely, by which time the smoke had dissipated. The aircraft taxied to its parking stand and the passengers and crew disembarked normally.
Subsequent examination of the No. 4 engine found a leak in an oil supply pipe, which is likely to have caused oil contamination of the bleed air supply used for air conditioning.

ACCIDENT: Piper PA-34 Seneca, EI-CMT Cork Airport, Co. Cork 29 May 2013: Report 2015-014
August 20, 2015
SYNOPSIS
During the landing roll the aircraft nose landing gear (NLG) retracted. The aircraft nose and both propellers contacted the runway surface. Damage to the aircraft was substantial. There were no injuries.
INCIDENT: Roko Aero NG4 UL, OK-TUR 22, Near Wicklow town, 30 December 2014 : Report 2015-013
July 6, 2015
SYNOPSIS
The microlight aircraft departed Newcastle Airfield (EINC), County Wicklow, with two pilots on board. The intention was to perform a short flight before returning to EINC. Approximately 20 minutes into the flight, a small amount of blue smoke was noticed in the cockpit, followed by a loss of engine oil pressure. The decision was made to carry out a forced landing and a suitable field was selected. To prevent engine damage, the Pilot shut down the engine during the approach to the chosen field.
The aircraft landed and came to rest without further incident. There were no injuries and the aircraft was undamaged. Subsequent examination revealed that a hose supplying engine oil to the engine oil cooler had disconnected in flight, resulting in the loss of all engine oil.
Two Safety Recommendations have been made as a result of this investigation.
