Boeing 737-200

The approach and landing in Iquitos was completed in heavy rain falls. After landing on a wet runway, the aircraft was unable to stop within the remaining distance, overran and came to rest with the right engine torn off. All 139 occupants were evacuated, among them 14 passengers were injured. The aircraft was damaged beyond repair.

The approach and landing at Lichinga Airport was completed in heavy rain falls. After touchdown, the aircraft suffered aquaplaning and was unable to stop within the remaining distance. It overran, lost a gear and an engine then came to rest few dozen meters further. All 108 occupants escaped uninjured while the aircraft was damaged beyond.

Indian Airlines B-737 aircraft VT-EAH was operating scheduled flight IC113 (Bombay - Ahmedabad sector) on 19-10-1988. There were 135 occupants on board including 6 crew members. Aircraft contacted Ahmedabad Approach Control at 0620LT. Ahmedabad weather as per Metar of 0540LT was passed to the aircraft and again at 0625LT (speci) of 0610LT was passed to the aircraft and then visibility has been reduced from 6 km to 3 km. Clearance to descend to FL150 was given at 0632LT and the aircraft was further cleared to FL55, 25 DME at 0636LT. At 0641LT, the aircraft was advised to report over Ahmedabad VOR and 'Speci' of 0640LT was also transmitted to the aircraft as per the same the winds were calm, visibility 2 km in haze and was 1010. QNH was correctly read back by the aircraft. The pilot decided to carry localiser-DME approach for runway 23 and reported overhead Ahmedabad. The aircraft went outbound and reported turning inbound. This was the last transmission from the aircraft and thereafter contact with the ATC was lost at 0650:53. The aircraft was found crashed at a distance of 2,540 meters from the beginning of runway 23 on the extended centre line of the runway in a paddy field at about 0653LT. Out of 135 persons on board, 133 received fatal injuries. The remaining two were seriously injured. The aircraft was destroyed due to post impact fire.

The approach to Port Harcourt Airport was completed in heavy rain falls. After touchdown, the airplane encountered difficulties to stop within the remaining distance and overran. While contacting soft ground, the nose and right main gear collapsed and the aircraft came to rest. 36 occupants were injured and the aircraft was damaged beyond repair.

While descending to Ushuaia Airport, the crew was informed about the weather conditions at destination: wind 230° at 12 knots, runway 16 in use, visibility 30 km, 3/8 SC at 1,200 meters, 2/8 CU at 1,500 meters, temperature 9° C, QNH 998,4 mb. After passing 8,000 feet on descent, the crew was cleared to land on runway 16 but the captain prefered to land on runway 34 as the last report indicated a wind from 360° gusting at 20 knots. Therefore, the crew was informed about possible windshear on approach. At an excessive speed of 140 knots (instead of the 128 knots as prescribed), the aircraft landed hard on runway 34 (positive acceleration of 1,89 G) and bounced. Out of control, it veered off runway, went down an embankment and came to rest in the sea (about two meters of water). All 62 occupants were evacuated, among them 13 were injured. The aircraft was destroyed.

Ethiopian Airlines flight 604, a Boeing 737-200, was a scheduled service from Addis Ababa to Bahar Dar and Asmara. The first leg of the flight was uneventful. At 09:50, the engines were started normally and the airplane was taxied to its take-off position. The flight crew reported that In order to gain additional thrust they elected not to use engine bleed air during take-off. The airplane accelerated at a normal rate during the take-off roll and passed V1 (take-off-reject) speed. As the airplane passed V1 and very near VR (rotation speed) the flight crew saw a flock of pigeons lifting up from the left side. At this time the captain took over control from the copilot and pulled up. Almost immediately after rotation, the airplane struck the flock of pigeons at an airspeed of 146 knots and altitude of 5730 feet above mean sea level. Loud bangs were heard. The captain then called for gear up and the copilot complied. At approximately 100-200 ft. above the ground, both engines started backfiring. At this time, the flight crew reported that they experienced a considerable power loss and the airplane started mushing down at which time the captain "fire walled" the thrust levers. The engines reportedly responded and the airplane began to gain some altitude. The gain in attitude encouraged the captain to make a right turn away from Lake Tana and back to the take-off runway for landing. During the initial 32 seconds after the impact, the airplane had gained altitude from 5,730 feet to 6,020 feet and had accelerated from 146 knots to 154 knots. The crew report further indicated that both engines continued to surge and the exhaust gas temperature gauges (EGT) were reading at the top extreme and the engine pressure ratio (EPR) gauge readings were fluctuating at about 1.6. During this time the captain reported that the he reduced engine thrust to prolong the operational life of the engines. The frequency of the surges decreased with engines power reduction. The airplane entered an approximate 90 degree right turn. Altitude remained constant 6,020 feet while its airspeed increased from 154 knots to 162 knots. The airplane then began another right turn and entered the downwind leg of the return to runway 04. Altitude had increased to 6,410 feet and airspeed to 173 knots. On the downwind leg the aircraft further climbed to 7,100 feet. Then, within a timeframe of about five seconds, both engines lost power completely. The copilot pointed out a cleared area slightly ahead and to the right. The captain then turned towards the clearing and performed a gear-up landing. The aircraft broke up and a fire erupted. Out of the 104 occupants, 35 suffered fatal injuries.

Indian Airlines flight IC422 was a domestic service from Srinagar to Delhi via Jammu and Chandigarh, India. The aircraft, a Boeing 737-200, landed gear up on runway 10 at Delhi-Indira Gandhi International Airport. The left engine then caught fire due to a fuel leak from ruptured fuel lines and a broken fuel control unit. The fire was quickly put out by fire services. All 134 occupants evacuated safely.

On April 28, 1988, an Aloha Airline Boeing 737, N73711, was scheduled for a series of interisland flights in Hawaii. The crew flew three uneventful roundtrip flights, one each from Honolulu to Hilo (ITO), Kahului Airport, HI (OGG) on the island of Maui, and Kauai Island Airport (LIH). At 11:00, a scheduled first officer change took place for the remainder of the day. The crew flew from Honolulu to Maui and then from Maui to Hilo. At 13:25, flight 243 departed Hilo Airport en route to Honolulu. The first officer conducted the takeoff and en route climb to FL240 in VMC. As the airplane leveled at 24,000 feet, both pilots heard a loud "clap" or "whooshing" sound followed by a wind noise behind them. The first officer's head was jerked backward, and she stated that debris, including pieces of gray insulation, was floating in the cockpit. The captain observed that the cockpit entry door was missing and that "there was blue sky where the first-class ceiling had been." The captain immediately took over the controls of the airplane. He described the airplane attitude as rolling slightly left and right and that the flight controls felt "loose." Because of the decompression, both pilots and the air traffic controller in the observer seat donned their oxygen masks. The captain began an emergency descent. He stated that he extended the speed brakes and descended at an indicated airspeed (IAS) of 280 to 290 knots. Because of ambient noise, the pilots initially used hand signals to communicate. The first officer stated that she observed a rate of descent of 4,100 feet per minute at some point during the emergency descent. The captain also stated that he actuated the passenger oxygen switch. The passenger oxygen manual tee handle was not actuated. When the decompression occurred, all the passengers were seated and the seat belt sign was illuminated. The No. 1 flight attendant reportedly was standing at seat row 5. According to passenger observations, the flight attendant was immediately swept out of the cabin through a hole in the left side of the fuselage. The No. 2 flight attendant, standing by row 15/16, was thrown to the floor and sustained minor bruises. She was subsequently able to crawl up and down the aisle to render assistance and calm the passengers. The No. 3 flight attendant, standing at row 2, was struck in the head by debris and thrown to the floor. She suffered serious injuries. The first officer tuned the transponder to emergency code 7700 and attempted to notify Honolulu Air Route Traffic Control Center (ARTCC) that the flight was diverting to Maui. Because of the cockpit noise level, she could not hear any radio transmissions, and she was not sure if the Honolulu ARTCC heard the communication. Although Honolulu ARTCC did not receive the first officer's initial communication, the controller working flight 243 observed an emergency code 7700 transponder return about 23 nautical miles south-southeast of the Kahalui Airport, Maui. Starting at 13:48:15, the controller attempted to communicate with the flight several times without success. When the airplane descended through 14,000 feet, the first officer switched the radio to the Maui Tower frequency. At 13:48:35, she informed the tower of the rapid decompression, declared an emergency, and stated the need for emergency equipment. The local controller instructed flight 243 to change to the Maui Sector transponder code to identify the flight and indicate to surrounding air traffic control (ATC) facilities that the flight was being handled by the Maui ATC facility. The first officer changed the transponder as requested. At 13:50:58, the local controller requested the flight to switch frequencies to approach control because the flight was outside radar coverage for the local controller. Although the request was acknowledged, Flight 243 continued to transmit on the local controller frequency. At 13:53:44, the first officer informed the local controller, "We're going to need assistance. We cannot communicate with the flight attendants. We'll need assistance for the passengers when we land." An ambulance request was not initiated as a result of this radio call. The captain stated that he began slowing the airplane as the flight approached 10,000 feet msl. He retracted the speed brakes, removed his oxygen mask, and began a gradual turn toward Maui's runway 02. At 210 knots IAS, the flightcrew could communicate verbally. Initially flaps 1 were selected, then flaps 5. When attempting to extend beyond flaps 5, the airplane became less controllable, and the captain decided to return to flaps 5 for the landing. Because the captain found the airplane becoming less controllable below 170 knots IAS, he elected to use 170 knots IAS for the approach and landing. Using the public address (PA) system and on-board interphone, the first officer attempted to communicate with the flight attendants; however, there was no response. At the command of the captain, the first officer lowered the landing gear at the normal point in the approach pattern. The main gear indicated down and locked; however, the nose gear position indicator light did not illuminate. Manual nose gear extension was selected and still the green indicator light did not illuminate; however, the red landing gear unsafe indicator light was not illuminated. After another manual attempt, the handle was placed down to complete the manual gear extension procedure. The captain said no attempt was made to use the nose gear downlock viewer because the center jumpseat was occupied and the captain believed it was urgent to land the airplane immediately. At 13:55:05, the first officer advised the tower, "We won't have a nose gear," and at 13:56:14, the crew advised the tower, "We'll need all the equipment you've got." While advancing the power levers to maneuver for the approach, the captain sensed a yawing motion and determined that the No.1 (left) engine had failed. At 170 to 200 knots IAS, he placed the No. 1 engine start switch to the "flight" position in an attempt to start the engine; there was no response. A normal descent profile was established 4 miles out on the final approach. The captain said that the airplane was "shaking a little, rocking slightly and felt springy." Flight 243 landed on runway 02 at Maui's Kahului Airport at 13:58:45. The captain said that he was able to make a normal touchdown and landing rollout. He used the No. 2 engine thrust reverser and brakes to stop the airplane. During the latter part of the rollout, the flaps were extended to 40° as required for an evacuation. An emergency evacuation was then accomplished on the runway.

The crew started the approach to Izmir-Adnan Menderes and the copilot was the pilot-in-command. He was cleared to the Outer Marker (CU NDB) then for an ILS approach to runway 35. After passing the NDB, the crew switched to ILS and thus couldn't verify his position while in the procedure turn. The aircraft was outside the 35° sector of the ILS centreline and the crew followed the wrong side beam. The aircraft descended too low and struck the slope of Mt Dümentepe (800 meters high) located about 18 km southwest of the airport. It disintegrated on impact and all 16 occupants were killed.
