16 March 1968
During a scheduled service from Yeşilköy Airport, Istanbul, Turkey to Diyarbakir, Turkey a major in-flight incident occurred: -
After taking off and reaching an altitude of 13,000 feet, rapid decompression occurred as a result of a failure of
the upper portion of the forward passenger door.
A third pilot, Captain Kemal Karapars, who was sitting in a stewardess seat near this door was sucked out, and the left-hand toilet bulkhead and closet were also ejected.
The port No.1 and No.2 propellers were damaged, causing the No.1 Rolls-Royce Dart engine to 'autofeather'. The No.2 propeller was manually feathered by the flight crew.
An approach was made to Gengistopel Military Airfield for an emergency landing, but during the final approach it was found that the starboard main undercarriage leg
would not lock down.
On landing, the starboard main undercarriage leg collapsed, and during the ensuing ground roll the aircraft was substantially damaged including curled starboard propeller blades
and shockloaded Rolls-Royce Dart engines as well as damage to the fuselage belly.
Among the remaining 4 crew and 49 passengers on board, some suffered minor injuries during the landing but the aircraft was safely evacuated.
After temporary repairs the aircraft was ferried unpressurised to Stansted Airport, Essex, England and repaired by Aviation Traders Engineering Ltd and returned to service.
19 March 1970
The aircraft was on approach to Esenboğa International Airport, Ankara, Turkey and after the undercarriage was lowered the pilots noted that the hydraulic pressure had dropped to zero.
After landing, the aircraft overshot the runway due to no brake pressure resulting in curled propeller blades and shockloaded Dart engines and damage to both wings.
There were no reported injuries to the passengers and crew on board.
The loss of hydraulic pressure was caused by the failure of a component located in the nose undercarriage bay.
Repaired and returned to service.
28 March 1972
Transferred to Türk Hava Kuvvetleri - Turkish Air Force.
