Manx2 Flight 7100 was a scheduled commercial flight from Belfast, Northern Ireland, to Cork, Republic of Ireland. On 10 February 2011, the Fairchild Metro III aircraft flying the route with ten passengers and two crew on board crashed on its third attempt to land at Cork Airport in foggy conditions. Six people, including both pilots, died. Six passengers survived but were injured, four of them seriously. Belfast Telegraph 11 February 2011.

The Air Accident Investigation Unit published its final report in January 2014. It stated that the probable cause of the accident was loss of control during an attempted go-around below decision height in instrument meteorological conditions (IMC). The report mentioned as contributory factors the inappropriate pairing of flight crews, inadequate command training and checking, and inadequate oversight of the charter operation by the operator and the operator's state.

History of the flight

Flight 7100 was scheduled to depart Belfast City Airport at 07:50 GMT arriving at Cork Airport for 09:00 GMT. On board were a crew of two and ten passengers.

The aircraft arrived at Belfast City Airport at 07:15 after a short positioning flight from Belfast International Airport, and was refuelled for the planned route-trip to Cork and back. The flight specified Waterford Airport as the alternate airport for the sector to Cork. No second alternate was made. Boarding of the flight was delayed due to both crew members working on the passenger seats in the cabin; boarding commenced once that task was completed. Passengers chose their seats at random and the safety demonstration was carried out by the co-pilot.

08:10 – Flight 7100 departed and was estimated to arrive in Cork at 09:10, where the weather was foggy. 08:34 – The flight crew established communication with Shannon Air Traffic Control. 08:48 – The aircraft was handed over to a Cork Approach controller. 08:58 – The crew reported established on the ILS for Runway 17 and was handed over to Cork Tower. 09:00 – Cork Tower passed on to the crew the instrumented runway visual range (IRVR), which was still below the minimum required. 09:03 – The crew descended below the decision height (DH) of and a missed approach (go-around) was carried out. The lowest recorded height on this approach was .

Radar vectors were given by Cork Approach to the reciprocal runway 35, which the crew believed with the sun behind the aircraft, might make visual acquisition of the runway easier.

09:10 – The aircraft was from touchdown and was handed back to Cork Tower. Again the RVR passed on by Tower were below minimums. The approach continued beyond the Outer Marker (OM). 09:14 – The aircraft again descended below the DH and a second missed approach was carried out. The lowest recorded height on this approach was . 09:15 – The flight crew entered a holding pattern named ROVAL and maintained an altitude of .

In the hold, the flight crew requested weather conditions for Waterford, which were below minimums. The flight crew nominated Shannon Airport as their alternate and requested the latest weather; again the weather there was below minimums. Weather for Dublin was passed on to the flight crew and was also below minimums. Cork Approach informed the flight crew about weather conditions at Kerry Airport, which were "good" with visibility.

09:33 – Flight 7100 was still in the ROVAL hold, IRVR for Runway 17 began to improve. 09:39 – Following further slight improvement in IRVR values, but with conditions still below minimums, the flight crew elected to carry out a third approach, and the second approach for Runway 17. 09:45 – Flight 7100 reported established on the ILS for Runway 17; during this time IRVR improved further to (the required minimum) which was passed on to the crew by Cork Approach. The flight was handed over to Cork Tower for the third time. 09:46 – Cork Tower passed on the latest IRVR of 500/400/400, which were now again below minimums.

The approach was continued beyond the OM, the commander taking over operation of the power levers. Descent was continued below the DH. A significant reduction in power and significant roll to the left followed, just below , and a third go-around was called by the commander, which the co-pilot acknowledged. Coincident with the application of go-around power by the commander, control of the aircraft was lost. The aircraft rolled to the left, and then to the right beyond the vertical, which brought the right wingtip into contact with the runway. The aircraft continued to roll and impacted the runway inverted. The stall warning sounded continuously during the final seven seconds of the CVR recording.

At 09:50:34, following both initial impacts the aircraft continued inverted for a further and came to a rest in soft ground to the right of the runway.

During this time, the Emergency Locator Transmitter (ELT) began to sound in the Control Tower at Cork Airport. Post impact fires ensued in both engines, and from fuel leaking from the outboard right fuel tank. The fires were put out by the Airfield Fire Service (AFS) before they reached the fuselage. Of the twelve on board, six people were fatally injured including both pilots. Four of the survivors suffered serious injuries whilst two received minor injuries and were described as walking wounded."First report on Cork crash expected next month." Raidió Teilifís Éireann. 11 February 2011. Retrieved on 11 February 2011. A witness inside the airport terminal building stated that the fog was so thick that the crashed aircraft could not be seen. The airport fire service extinguished both post impact fires within ten minutes of the accident, and started to remove the casualties from the wreckage. The injured were taken to Cork University Hospital for treatment.

Aircraft and crew The aircraft destroyed in the accident was a twin-turboprop Fairchild SA227-BC Metro III with Spanish registration EC-ITP, c/n BC-789B, It was owned by a Spanish bank and leased to Líneas Aéreas de Andalucía, known as Air Lada, based in Seville, Spain. The aircraft was subleased to Flightline S.L., based in Barcelona, Spain, and was on its air operator's certificate (AOC). Tickets were sold by a company called Manx2, which was based in the Isle of Man. The aircraft was 19 years old at the time of the accident, and it had undergone a maintenance check in the week prior to the accident.

The captain was 31-year-old Jordi Sola Lopez from Barcelona, Spain. The first officer was 27-year-old Andrew John Cantle from Sunderland, England. Both were employed by Air Lada. The captain had logged 1,800 total hours of which 1,600 were on the Fairchild Metro III, but just 25 were as pilot-in-command on the aircraft. The first officer had logged 539 total hours of which 289 were on the aircraft type. Their pairing together on the flight was considered inappropriate and highly unusual due to their shared lack of total experience. Both pilots were certified for Instrument landing system CAT I; neither pilot, however, was certified for CAT II.

Sola Lopez had been promoted to captain on 4 February 2011. His first flight in command of the aircraft took place on 6 February 2011, four days prior to the accident. The captain had flown into Cork 61 times; his logbooks had never shown any diversions.

The first officer had joined another Spanish operator flying the Fairchild Metro III for 270 hours before joining Air Lada. According to the logbooks, he subsequently flew with line captains who were not instructors. He accumulated 19 hours with Air Lada, but he never completed the line check although he had been required to do so.

Investigation The Air Accident Investigation Unit (AAIU) opened an investigation into the accident. Four personnel from the AAIU were on scene within 90 minutes of the accident. They completed their survey of the wreckage that day. The cockpit voice recorder (CVR) and flight data recorder (FDR) were recovered from the wreckage. The data from the FDR was extracted by the AAIU in Dublin, while the CVR was sent to the UK's Air Accident Investigation Branch (AAIB) for download. There were accredited representatives to the team from the United States FAA and NTSB, the Aviation Incidents and Accidents Investigation (AIAI) of Israel (as the "State of Type Certificate Holder"), Spain's Civil Aviation Accident and Incident Investigation Commission and the British AAIB.

The wreckage was transported to the AAIU's examination facility at Gormanston, County Meath, to allow investigators to reconstruct the aircraft as far as possible. The six survivors were interviewed by the AAIU.

A preliminary report, issued in March 2011, stated that the aircraft, being flown by the co-pilot, had deviated from the runway centre-line on final approach and that the crew decided to execute a third go-around four seconds before impact. The aircraft rolled to the left and to the right, and the right wing then impacted the runway.

An interim statement was published in February 2012 in line with European Union regulatory requirements. Inspection of the engines revealed that the right engine had consistently been developing up to five percent more torque than the left engine, as a result of a defective right engine intake air temperature and pressure sensor. The defective sensor meant that as well as delivering more torque than the left engine it would also respond more rapidly to commands to increase power from the engine's power lever than the left engine. The investigation also determined that both engines were developing go-around power at the moment of impact, having both been below flight idle power at eight to six seconds before impact. At eight seconds before impact the right engine reached a minimum of zero torque while the left engine reached −9 percent torque (which means the left propeller was driving the engine instead of the engine driving the propeller). The stall warning horn also sounded repeatedly in the seven seconds prior to impact.

Final report The AAIU released its final report on the accident in January 2014. The probable cause was stated as loss of control during an attempted go-around below decision height in instrument meteorological conditions.

The final report included 54 findings, found 9 contributing factors, and made 11 safety recommendations.

Operation of the accident aircraft Manx2's Belfast-Cork route was operated on the air operator's certificate (AOC) of Flightline. As such, Flightline was responsible for controlling all operational matters relating to that service. In practice many day-to-day decisions were taken by Manx2 in its Isle of Man office. One such decision was the pairing of Lopez and Cantle to crew flight 7100 on 10 February. Correct adherence to European aviation regulations (EU-OPS) by the AOC-holder should have prevented this inappropriate pairing of a newly promoted captain with a relatively inexperienced first officer. It had come about because Cantle was drafted in to replace the pilot who was originally rostered as first officer for the flight when he became unavailable. Flightline was not aware of the change in personnel.
