Circumstances:
The airplane, owned by the Islamic Republic of Iran Air Force (IRIAF) was completing a cargo flight from Bishkek, Kyrgyzstan, on behalf of Saha Airlines, and was supposed to land at Payam Airport located southwest of Karaj, carrying a load of meat. On approach, the crew encountered marginal weather conditions and the pilot mistakenly landed on runway 31L at Fath Airport instead of runway 30 at Payam Airport which is located 10 km northwest. After touchdown, control was lost and the airplane was unable to stop within the remaining distance (runway 31L is 1,140 meters long), overran and crashed in flames into several houses located past the runway end. The aircraft was destroyed by fire as well as few houses. The flight engineer was evacuated while 15 other occupants were killed.

Circumstances:
Crew was engaged in a refuelling mission for USAF FA/18 around Point Mugu Naval Air Station. During take off roll, captain started rotation at a speed of 150 knots and after a distance of 7,000 feet. At a height of twenty feet above the ground, the number two engine speed lever went back to idle position. Crew decided to land but aircraft was unable to stop within the remaining distance available. It overrun, lost its landing gear and engines number one, two and four before coming to rest in flames in a marshy field. Aircraft was destroyed by impact forces and post impact fire feed by 150,000 pounds of fuel. All three crew were slightly injured.

Circumstances:
The Aircraft was operating a flight from Sharjah International Airport, UAE to Khartoum International Airport, Sudan, with a total of six persons on board: three flight crew members (captain, co-pilot, and flight engineer), a ground engineer, and two load masters. All of the crew members sustained fatal injuries due to the high impact forces. Sometime after of liftoff, the core cowls of No. 4 engine separated and collapsed onto the departure runway, consequently No. 4 Engine Pressure Ratio (“EPR”) manifold flex line ruptured leading to erroneous reading on the EPR indicator. The crew interpreted the EPR reading as a failure of No. 4 engine; accordingly they declared engine loss and requested the tower to return to the Airport. The Aircraft went into a right turn, banked and continuously rolled to the right at a high rate, sunk, and impacted the ground with an approximately 90° right wing down attitude.
Probable cause:
The Investigation identified the following Causes:
(a) the departure of the No. 4 engine core cowls;
(b) the consequent disconnection of No. 4 engine EPR Pt7 flex line;
(c) the probable inappropriate crew response to the perceived No. 4 engine power loss;
(d) the Aircraft entering into a stall after the published maximum bank angle was exceeded; and
(e) the Aircraft Loss of Control (“LOC”) that was not recoverable.

Contributing Factors to the Accident were:
(a) the Aircraft was not properly maintained in accordance with the Structure Repair
Manual where the cowls had gone through multiple skin repairs that were not up to
aviation standards;
(b) the Operator’s maintenance system failure to correctly address the issues relating to the No. 4 engine cowls failure to latch issues;
(c) the failure of the inspection and maintenance systems of the maintenance organization, which performed the last C-Check, to address, and appropriately report, the damage of the No. 4 engine cowls latches prior to issuing a Certificate of Release to Service;
(d) the Operator’s failure to provide a reporting system by which line maintenance personnel report maintenance deficiencies and receive timely and appropriate guidance and correction actions;
(e) the Operator’s quality system failure to adequately inspect and then allow repairs that were of poor quality or were incorrectly performed to continue to remain on the Aircraft; and
(f) the SCAA safety oversight system deficiency to adequately identify the Operator’s chronic maintenance, operations and quality management deficiencies.

Circumstances:
Shortly after take off, engine number two suffered an uncontained failure. Crew informed ATC of the situation and obtained the authorisation to return in priority. Aircraft landed safely ten minutes later. While two passengers were slightly injured, aircraft was considered as damaged beyond repair as number one engine and left wing were also damaged.
Probable cause:
It appears that a stage of the compessor on number two engine exploded shortly after take off. Elements punctured the nacelle and hit the left wing and the number one engine. As the number two engine was out of service, number one lost power.
