What happened
On 9 May 1999, a Jodel DR 1050, registration G-AZAD, was conducting a series of local sightseeing flights near Dornoch, Scotland. The pilot, accompanied by his wife, had been operating the aircraft from Inverness airport as part of a syndicate. Following two successful sightseeing excursions for family friends, the pilot prepared for the return leg to Inverness.
At 1512 hrs, the aircraft departed Dornoch. During the flight, the pilot communicated with Inverness tower, reporting his position near the Nigg oil rig fabrication yard. At this time, he noted he was still flying under Visual Meteorological Conditions (VMC) with a cloud base of approximately 400 feet. However, air traffic controllers subsequently advised the pilot of a very low cloud base in the vicinity of Fort George and the Beauly Firth.
Witnesses in the town of Cromarty observed the aircraft performing steep turns, banking at angles between 45° and 50° while circling into the mist. A second witness, located on higher ground, observed the aircraft flying extremely low, following the contours of the terrain. The aircraft was seen dipping its wings before disappearing over a hill crest at a height of only half that of nearby trees. Shortly thereafter, the aircraft struck the ground, resulting in two fatalities.
The investigation
AAIB investigators examined the wreckage found in a waterlogged depression at an altitude of 340 feet amsl. The aircraft was found inverted, having struck the ground on a heading of approximately 280° before rotating. The investigation focused on the mechanical condition of the Jodel DR 1050 and the environmental factors present at the time of the accident.
Engine analysis revealed the Continental 0-200-A engine was mechanically sound, with no evidence of malfunction in the carburettor or accessory drives. The propeller damage indicated the engine was at low power during impact. While the airbrakes were found slightly drooped, investigators found no evidence of pre-impact failure in the flight controls or any mechanical reason for the loss of control.
Findings
- The pilot was attempting to return to Inverness while maintaining VMC, which required avoiding low cloud layers.
- The pilot was not trained or qualified for instrument flight.
- The pilot became disoriented while maneuvering in low visibility, leading the aircraft into rising ground.
- It is possible the aircraft experienced an inadvertent stall as speed decreased during a climb.
