Accident Details
On 8 May 2017 at 1401 UTC, a single-engine MTOsport gyroplane (G-HOTC, serial no. RSUK/MTOS/058) sustained damage during a takeoff attempt on Runway 09 at Shobdon Aerodrome, Herefordshire. The aircraft was operated on a private flight with one pilot and no passengers.
Sequence of Events
According to the pilot's report, before takeoff the pre-rotator had spun the main rotor to approximately 150-160 rpm, which was below the normal speed of 200 rpm. Despite this, the pilot elected to commence the takeoff. As the gyroplane accelerated, increasing control forces were required to maintain the runway centreline. The aircraft then pitched nose-up and rolled to the left, causing the main rotor blade tips and rear stabiliser to contact the runway surface. The pilot subsequently aborted the takeoff.
Injuries and Damage
No injuries were reported among the crew. The aircraft sustained abrasion damage to the rotor blade tips and rear stabiliser.
Pilot Information
The 57-year-old pilot held a Private Pilot’s Licence and had accumulated 397 flying hours, of which 124 were on type. His recent flying experience included 18 hours in the last 90 days and 5 hours in the last 28 days.
Pilot's Explanation
The pilot attributed the accident to his decision to continue the takeoff attempt with less than 200 rotor rpm, combined with applying power too quickly, which created a ‘blade flap’ situation.
