What happened
On 22 May 2011, a Britten-Norman BN2A-26 Islander, registration VP-MON, was performing a scheduled passenger flight from Antigua to Montserrat. During the landing on Runway 28, the pilot experienced a skid upon the initial application of the brakes. Fearing the aircraft would overrun the paved surface, the pilot steered the aircraft onto a grass verge. The aircraft eventually came to rest 46 metres from the end of the runway. There were no injuries, and the aircraft sustained damage.
Investigation findings
The investigation identified several contributing factors related to the airport environment and operational procedures. While the aircraft's braking system was functional, the aircraft was operating in an environment where the runway surface was damp. The investigation also noted that the aircraft was operating with a weight that, while within limits, contributed to the landing dynamics.
Furthermore, the investigation highlighted issues regarding the airport's infrastructure and procedures. The lack of recent wind monitoring equipment at the threshold meant the pilot may not have been fully aware of the wind conditions. Additionally, the investigation found that the airport's approach lighting and the placement of the visual aids could potentially lead to challenges during certain weather conditions. The investigation also noted that the pilot's familiarity with the specific runway characteristics at this airport was a factor in the outcome.
Safety recommendations
The investigation concluded that the incident was caused by a combination of environmental factors and operational limitations. To prevent a recurrence, the investigation recommends that the airport authority review its wind monitoring capabilities and consider the installation of more visible wind indicators. Additionally, a review of the approach procedures and the maintenance of runway surface friction levels is recommended to ensure safe operations during damp conditions.
