DARTMOUTH, NS, Nov. 12, 2013 /CNW/ - The Transportation Safety Board of
Canada (TSB) today released its investigation report (A11A0101) into
the 10 December 2011 aborted take-off of a Hawker Beechcraft 1900D
operated by Exploits Valley Air Services Ltd. at the Gander
International Airport in Newfoundland and Labrador.
The 2 crew members were preparing to depart on a flight from Gander to
Goose Bay, Newfoundland and Labrador, with 13 passengers on board.
After the crew began the take-off roll, they noted that the control
column was stuck in the full forward position. The take-off was
aborted, and the aircraft was taxied back to the terminal to unload the
passengers and then to the operator's hangar for further examination.
There were no injuries to the passengers or crew.
It was determined that before the flight, the aircraft had been parked
outside in gusty wind conditions without control locks installed. This
caused the elevator control to slam down repeatedly and eventually
become jammed against a stop bolt designed to limit its downward
travel. The stuck control was not detected before take-off, since an
elevator control check was not carried out as part of the maintenance
daily inspection or the after-engine-start checklist.
The manufacturer issued communiqués to advise readers of similar
occurrences; however, the information provided by the manufacturer was
not clear or concise, and thus there was a risk that operators may not
fully understand the safety and risk-mitigation measures to be taken.
Additionally, operators such as Exploits Valley Air Services are not
required to have a safety management system (SMS) similar to larger
operators. As such, there is an increased risk that hazards will not be
identified and mitigated.
Following this occurrence, the operator requires that flight control
locks be used any time there isn't a crew member at the controls. The
US FAA issued an Emergency Airworthiness Directive, effective
immediately upon receipt, that requires operators to examine the
elevator control system. Hawker Beechcraft has issued a service
bulletin for Model 1900-series aircraft, and provides parts and
instructions to install a second stop bolt for the elevator control.
Air safety management systems are a TSB Watchlist issue. Watch the TSB video!

advancement of transportation safety. It is not the function of the
Board to assign fault or determine civil or criminal liability.
