Narrative:The Glasgow based Islander aircraft was engaged on an air ambulance task for the Scottish Ambulance Service when the accident occurred. The pilot allocated to the flight had not flown for 32 days; he was therefore required to complete a short flight at Glasgow to regain currency before landing to collect a paramedic for the flight to Campbeltown Airport.
Poor weather at Campbeltown Airport necessitated an instrument approach. There was neither radar nor Air Traffic Control Service at the airport, so the pilot was receiving a Flight Information Service from a Flight Information Service Officer in accordance with authorised procedures. After arriving overhead Campbeltown Airport, the aircraft flew outbound on the approach procedure for runway 11 and began a descent. The pilot next transmitted that he had completed the ‘base turn’, indicating that he was inbound to the airport and commencing an approach. The airplane had gradually descended below the minimum altitude With a slight left wing low attitude, the airplane contacted the sea. It broke up after impact and sank.
Probable Cause:
CAUSAL FACTORS:
"1. The pilot allowed the aircraft to descend below the minimum altitude for the aircraftÂ’s position on the approach procedure, and this descent probably continued unchecked until the aircraft flew into the sea.
2. A combination of fatigue, workload and lack of recent flying practise probably contributed to the pilotÂ’s reduced performance.
3. The pilot may have been subject to an undetermined influence such as disorientation, distraction, or a subtle incapacitation,which affected pilotÂ’s ability to safely control the aircraftÂ’s flightpath."
Classification:
Insufficient rest / fatigue
Controlled Flight Into Terrain (CFIT) - Water

Follow-up / safety actions
AAIB issued 3 Safety Recommendations
Issued: -- | To: EASA and JAA | 2006-101 |
The European Aviation Safety Agency and Joint Aviation Authorities should review the UK Civil Aviation AuthorityÂ’s proposal to mandate the fitment of Upper Torso Restraints on all seats of existing Transport Category (Passenger) aeroplanes below 5,700 kg being operated for public transport, and consider creating regulation to implement the intent of the proposal. (Accepted - closed) |
Issued: -- | To: CAA UK | 2006-102 |
Considering the unique circumstances of air ambulance flights, the Civil Aviation Authority, in conjunction with the Joint Aviation Authorities should review the circumstances in which a second pilot is required for public transport flights operating air ambulance services. |
Issued: -- | To: CAA UK | 2006-103 |
The Civil Aviation Authority, in conjunction with the Joint Aviation Authorities, should consider mandating the carriage of a radio altimeter, or other independent low height warning device, for public transport IFR flights operating with a single pilot. |
