Fatal Light Aircraft Crash Involving Gifted Flight Experience
One of the two men who died in a light aircraft crash was participating in a gifted introductory flight experience, according to an air accident report.
Pilot Edward Browne, aged 66, and passenger James Litchfield, aged 64, lost their lives when the Hoffmann H36 Dimona aircraft crashed shortly after take-off from Darley Moor Airfield in Derbyshire on 8 April 2025.
Investigation Findings by the Air Accidents Investigation Branch
The Air Accidents Investigation Branch (AAIB) reported that investigators were unable to determine the exact cause of the crash but identified the aircraft's weight at take-off as a contributory factor.
It was estimated that the aircraft exceeded the recommended maximum take-off weight of 170.6kg (376lb) by more than 35kg (66lb), with a total payload of approximately 206kg (454lb).
The report, released on Thursday, confirmed that the flight was an introductory experience purchased for passenger James Litchfield by a family member.
Sequence of Events Leading to the Crash
Witnesses observed the aircraft shortly after take-off at low altitude, noting that it began swaying side to side before rolling sharply to the right and descending rapidly to the ground.
The AAIB described the injuries sustained by both men as "unsurvivable."
Recorded flight data indicated that the take-off proceeded as expected; however, the pilot was unable to maintain a safe climbing speed or trajectory thereafter.
The observed movements were consistent with the aircraft being at or near a stall condition.
Conclusions and Unresolved Factors
Investigators concluded that they could not determine why the aircraft failed to climb normally or what factors prevented the pilot from executing a successful landing once the climb performance was compromised.
The investigation found no evidence of technical issues affecting engine performance, and analysis of the aircraft's controls suggested that an accidental throttle reduction by the pilot was unlikely.
Despite the aircraft exceeding its maximum approved weight at take-off, investigators classified this as a contributory rather than causal factor in the accident.
Operational and Procedural Observations
Investigators noted the absence of documented weight and balance calculations by the pilot on the day of the crash. Although the pilot was observed preparing the aircraft for flight, the daily inspection logbook for the plane had not been signed.
Responses and Safety Measures Following the Report
In response to the AAIB report, the flight operator, which remains unnamed, has revised its flight booking procedures to require customers to complete an online data capture and flight waiver form prior to scheduling any flight experience.
Declared boarding weights on these forms are now verified at the airfield before a passenger's initial flight.
The British Gliding Association (BGA) has issued communications to its member clubs, reiterating guidance on introductory flights and emphasizing the importance of thorough flight preparation.
The BGA also plans to issue a notice to all its inspectors highlighting the necessity of identifying all relevant information, including limitations related to non-lifting parts, when compiling aircraft weighing reports.
