BOMBARDIER INC BD-100-1A10 near Wheeling, IL — 2010-02-24

Probable cause

The deicing vehicle operator's not adhering to company procedures and not maintaining clearance between the vehicle's boom and the airplane's empennage during the airplane's deicing operation.

NTSB narrative

According to the pilot, their executive jet airplane was undergoing deicing operations following their taxi to a run up pad near runway 34 and taxiway kilo, in preparation for departure. As the deicing truck was conducting the procedure, the vehicle's boom struck the airplane's empennage causing substantial damage. The fixed base operator’s [FBO] deicing/anti-icing training guidebook states that the driver should “always know where the boom and bucket are located.” There were supervisors on duty at the airport during the deicing operation; however, no supervisor was specifically overseeing the deicing operation. The FBO’s training guidebook did not require that a supervisor oversee deicing operations.
