BN2-A Mk III-2 Trislander, G-BEVT

Summary:

Following an accident where a propeller de-icer boot separated and penetrated a window, injuring a passenger, the AAIB investigated a subsequent de-icer boot separation on the same aircraft. The investigation found that the quality of the adhesive bond between the boot and the blade is dependent upon meticulous adherence to correct procedures and practices. No safety recommendations are made because, industry wide, satisfactory attachment of the boots is routinely achieved using published procedures and correct materials. However, apparently quite minor deviations in the process can cause a reduction in bond strength which can lead to boot separation.
