What happened
On 19 November 2005, a Stampe SV4C(G), registration G-BWEF, was involved in a ground collision at Redhill Aerodrome. Following a landing on Runway 08L, the pilot was cleared by Air Traffic Control to taxi via Taxiway ‘A’ toward the western parking area. As the aircraft reached the threshold of Runway 19, the pilot initiated a left turn. During this manoeuvre, the lower right wing of the aircraft struck marker board G3, which was used to indicate the holding position for Runway 1s. There were no injuries to the two occupants, though the aircraft sustained damage to its right wing.
The investigation
The AAIB examined the positioning and visibility of the marker board in question. The investigation confirmed that board G3, which had been installed in August 2005, was correctly placed in accordance with CAP 168 regulations and was properly notified to aerodrome users. The pilot noted that while the board was known to him, its side-on visibility was difficult and suggested the use of more frangible materials. The investigation also looked into the communication between the aerodrome authority and local flying organisations, finding that while changes were communicated via email and the aerodrome website, formalised regular dialogue had lapsed.
Findings
- The pilot's lookout from the rear cockpit was inadequate, which is a common challenge in tailwheel aircraft due to restricted forward visibility.
- The marker board was positioned correctly according to regulatory standards, but its visibility when viewed from the side was limited.
- There was a lack of effective, regular formal communication between the aerodrome authority and home-based flying organisations.
Safety action
- Redhill Aerodrome Limited committed to consulting with local flying training organisations regarding the benefits of re-establishing a User’s Committee to monitor operating procedures.
