What happened
On the night of 14 November 2011, a Cessna T210N, registration XB-LLD, crashed on the island of Cayman Brac. The aircraft, which had been flying from Mexico via Belize, was observed by a resident crossing the coast from south to north. The aircraft was not displaying any lights, making it difficult to see. Witnesses reported hearing the engine noise decrease and then sharply increase, suggesting an attempted go-around.
The pilot attempted to land on an unlit, straight road. During the approach, the left wingtip struck a wooden pole, leading to a sequence of impacts with trees and another pole. The force of the impact, particularly with a pole on the aircraft's nose, caused the engine to detach and the aircraft to perform a cartwheel. Both crew members sustained two fatal injuries.
The investigation
The investigation examined the wreckage, recovered documents, and GPS data. Investigators found that the aircraft had undergone a significant amateur modification to its fuel system. To extend its range, ten 60-litre containers were placed in the cabin, connected to the wing tanks via hoses and electric pumps. These pumps were wired to the aircraft's 'flood lights' and 'pitot heat' switches.
Analysis of the GPS units showed the flight track ended 300 nm short of its intended destination. The investigation also looked into the condition of the electrical system, noting that several circuit breakers, including the alternator breaker, were missing or tripped. The engine was found to be in good condition, and the turbocharger showed evidence of power being developed at the time of impact.
Findings
- The aircraft likely suffered an electrical failure that prevented the use of the modified fuel system.
- The crew may have deviated from their original flight path, possibly intending to divert to Cuba, which brought them over Cayman Brac.
- The landing was attempted on an unsuitable road surface following the loss of electrical power or an intention to remain unobserved.
- The aircraft struck utility poles during the landing attempt, leading to the loss of control and the destruction of the aircraft.
