Some aircraft have gust locks fitted as part of the control system.

The gust locks had not been removed before flight and the aircraft was overloaded.

They determined that the gust lock cables slapping against the ceiling panel had produced the noise.

The aileron gust lock was not removed prior to flight, resulting in loss of control after takeoff.

The cause of the accident was that flight was attempted with the rudder and elevator gust locks in place.

The crash of Air Indiana Flight 216 occurred due to failure to remove the gust locks.

The crash was determined to be due to pilot error, as the pilot had not removed the control gust lock prior to taking off.

The accident was due to the elevator gust lock having become re-engaged, preventing the aircraft from rotating into a flying attitude.

Gust locks are often used on parked aircraft with mechanical systems to protect the control surfaces and linkages from damage from wind.

The remainder of the fleet was checked and all gust locks were found to be out of rig and tension.

Investigation into the accident revealed that the aircraft's elevator and rudder gust locks had not been disengaged prior to departure.

That the gust lock system be redesigned to ensure positive operation at all times and avoid misleading the crew as to the position of any lock.

When the off-duty pilot deactivated the gust lock, the aircraft went into a steep dive, executed part of an outside roll and became inverted.

A gust lock can pose a serious safety hazard if its removal is omitted before an aircraft's takeoff, because it renders the flight control inoperative.

A C-124 transport carrying US servicemen home for Christmas crashed in 1952 due to engagement of gust locks.

Many internal gust locks have a safety feature that locks out the aircraft's throttle or engine-start controls until removed and stowed.

The aircraft was departing to Atlantic City, New Jersey when it failed to take off because the gust lock was left engaged.

The cause of the accident was that the gust locks had not been removed and the aircraft was improperly loaded, resulting in an aft CoG.

Gust locks prevent wind from causing unexpected movements of the control surfaces and their linked controls inside the aircraft, as well as aircraft doors on some aircraft.

While the flight was approaching Dhaka Tejgaon Airport, the hydraulic gust lock system activated in flight, causing the controls to lock.

As these many tragedies (and this is far from a complete list) illustrate, when a gust lock is used, its disengagement is a very important step on the preflight checklist.

Examination revealed that a lack of appropriate lubrication of the gust lock mechanism resulted in the lock pin associated with an elevator circuit cable quadrant to most likely 'hang up'.

A gust lock on an aircraft is a mechanism that locks control surfaces and open aircraft doors in place while the aircraft is parked on the ground and non-operational.

The crew forgot to disengage the "gust locks", a system of devices integral to the design that held the bomber's movable control surfaces in place while the aircraft was parked on the ground.
