What happened
On 13 July 2023, a Cessna 208B, registration G-EELS, was performing a specialised operations flight at Perth Airport. The aircraft was carrying a pilot and a camera operator to film a golf event. During the taxi phase, the window was opened to provide ventilation for the passenger.
While preparing for departure from Runway 21, the pilot was monitoring circuit traffic. As the takeoff roll commenced, the pilot advanced the power lever; however, he noted significant noise within the cockpit, potentially due to the open window or the headset not being properly engaged. Although the engine sounded as though it was at maximum power, the pilot did not verify the engine instruments due to distractions caused by observing other aircraft in the circuit.
The aircraft rotated at 75 kt, but airspeed dropped to 65 kt immediately after liftoff. After briefly remaining in ground effect, the aircraft touched down on the runway again. Fearing insufficient thrust to climb, the pilot decided to reject the takeoff. To avoid a small ditch located at the end of the runway, the pilot performed a second rotation to clear the obstacle. The aircraft eventually came to rest in a field of standing crop. There were no injuries to the crew or passenger, though the propeller sustained minor tip damage.
The investigation
The AAIB examined the engine and propeller following the incident. Inspections were conducted according to manufacturer guidelines, and subsequent engine runs revealed no mechanical faults or performance deficiencies. The aircraft was subsequently returned to service after repairs to the propeller blades were completed.
Findings
- The pilot was distracted by monitoring circuit traffic during the takeoff roll.
- The cause of the perceived lack of engine power could not be determined as no mechanical faults were identified during post-incident testing.
