What happened
On 12 August 2000, a Reims Cessna F177RG, registration G-BFGF, was conducting a private flight near Ingoldmells, Lincolnshire. During the flight, the aircraft's radio failed, preventing the pilot from communicating on the air/ground frequency.
Following the loss of radio contact, the pilot circled the airfield and initially attempted an approach to Runway 21. After performing a go-around, the pilot repositioned the aircraft for an approach to Runway 30. This second approach was characterized by excessive speed and altitude; however, the pilot determined that the landing was viable and that the remaining runway length was sufficient.
Upon touchdown on the dry grass surface, the aircraft failed to decelerate at the anticipated rate. The pilot attempted a second go-around by selecting the flaps up, but realized the maneuver was being executed too late. Choosing to remain on the ground, the aircraft overran the runway and came to a stop in a ditch. Both occupants, the pilot and one passenger, sustained minor injuries. While the pilot was able to exit through his door, the passenger became trapped by their feet due to a jammed door, requiring assistance from the pilot to escape.
The investigation
The investigation established that the pilot experienced confusion regarding bollards located at the threshold of the initial approach runway. Furthermore, the loss of radio communication was identified as a potential source of distraction during the landing sequence.
