Narrative:
Written off (damaged beyond repair) 12.5.1984 when collided at 3,000 feet over Longdon, near Tewkesbury, Gloucestershire with Schmepp-Hirth Standard Cirrus 75 glider BGA 2138. The pilot of Rockwell Commander G-BIOU was slightly injured, but the pilot of the Cirrus glider BGA 2138 was killed.

The Rockwell Commander G-BIUO was flying straight and level at 3,000 feet and 125 knots between Cardif/Rhoose Airport and Humberside Airport on a properly-filed VFR flight plan.

The Cirrus BGA 2138 had taken off from Bidford-on-Avon at 11:05 hours, with a flight plan from Bidford-on-Avon to overhead at Raglan Castle, near Monmouth, and return to Bidford-on-Avon at IAS of approximately 70 knots.

The two aircraft were seen to collide at 14:35 hours; as a result of the impact collision, the port wing of the Cirrus glider detached, while the remainder of the glider spiralled earthwards, breaking up and ejecting the pilot, who was killed. The pilot of the Cirrus glider had a parachute, but did not deploy it. It is not clear if he was conscious after the collision, but if he was unconscious, that may explain why he did not use his parachute.

The Rockwell Commander, meanwhile, lost its propeller and engine cowling in the impact. The windscreen was crushed inwards; the tail empennage, as well as being distorted, suffered several fractures of the supporting spar attachments to the fuselage. The rear fuselage also received a compression distortion on the left hand side.

Despite the severity of the damage, and the force of the impact, the pilot of the Rockwell Commander managed to regain control, and execute a safe landing in a meadow at Longdon, Gloucestershire. The aircraft undershot the intended touchdown point, and received further damage when it collided with a barbed wire fence and a fence post. When the aircraft came to a halt, the engine was still running.

The subsequent AAIB investigation concluded that the Cirrus glider had caused the collision by landing on top of the Rockwell Commander from the right hand side at an angle of 30 degrees. It was concluded that the pilot of the Cirrus had not seen the Rockwell Commander until the last moment, when it was too late to taking avoiding action. The pilot of the Rockwell Commander was unaware of the Cirrus until the collision impact.

Registration of the Rockwell Commander G-BIUO was belatedly cancelled by the CAA on 10.1.1989 as "destroyed"

Longdon is a village and a civil parish in the Malvern Hills District and council ward of the county of Worcestershire, England and lies about 5 km (3 miles) south of Upton-on-Severn. It is jointly administered with two other parishes by Longdon, Queenhill and Holdfast Parish Council. Despite this, the AAIB Report gives the crash location as "near Tewkesbury, Gloucestershire"

NOTE: The official AAIB report gives the registration of the Cirrus glider as "BGA 610", but this is an error - the "610" was the competition number worn by the airframe at the time of the crash. The actual BGA registration was BGA 2138
