garuda flight 421 death


The ditch procedure was successful, leaving the aircraft settled down on its belly in the shallow water, with the fuselage, wings and control surfaces largely intact. When they started APU, the battery simply went dead and the crew lost all electronics on board.

Reports I read indicated not only did the aircraft penetrate a super cell with likely tops above 50,000 feet but the noise of the rain recorded by the CVR indicated it was the heaviest rain ever recorded and beyond engine certification levels. After evacuation, the pilot contacted the Jogja Tower via cellphone and reported the emergency landing and location. A later Safety Recommendation letter[4] from the U.S. NTSB to the FAA notes that analyses of flight recorder data and weather satellite images indicate that the aircraft had already entered a thunderstorm cell at the start of the diversion to avoid the storm. It was probable that the flight path of the aircraft during weather de-tour when flying into the gap went toward radar shadow cause by an excessive amount of active weather cells in that area. It was due to inadequacy in the battery maintenance procedures. This writer knows from experience of flying a dead stick landing in the 737 simulator that most pilots would crash by either severe undershoot or overshoot if faced with the circumstances of the Garuda crew – if they had not practiced the event in a simulator. Ditching at 180 knots touch down speed with no flaps and no power would have even eclipsed Sullenberger’s wonderful feat of airmanship. On January 16, 2002, at approximately 09:24 UTC, Garuda Indonesia flight GA421 , a Boeing 737-300, PK-GWA, ditched into the waters of the Bengawan Solo River, Central Java during a forced landing, following loss of power on both engines as the aircraft was descending through 19,000 ft. All data and information provided on this site is for informational purposes only. The aircraft descended from cruise altitude of 31,000 ft to 28,000ft as instructed by BALI ATC at 09.08 UTC due to traffic on eastbound at FL290. The investigation into the ditching of Garuda Indonesia Flight 421 was lead by the Indonesian National Transportation Safety Committee (NTSC). Jan 16 2017. For instance, they waited only about 1 minute between each restart attempt instead of 3 minutes. As they began their descent from FL 280 at 09.13 UTC, prior to entering the clouds at 23,000 feet, the crew noted at the radar screen red cells with two green and yellow areas to the left and right of their intended flight path. The aircraft, Garuda Indonesia flight GA 421, had departed Ampenan at 08:32 UTC, on a regular scheduled commercial flight with destination Yogyakarta. Total: Fatalities: 1 / Occupants: 60. We'll assume you're ok with this, but you can opt-out if you wish. The ditch procedure was successful leaving the aircraft settled down on its belly in the shallow water, with the fuselage, wings and control surfaces largely intact. There were thirteen (13) injuries and one fatality — mostly due to the impact with the riverbed, which also damaged the aircraft. The corrosion happened sometimes before the accident, and was not caused by the submersion in the river. The crew carried out three unsuccessful attempts to restart the engines followed by one unsuccessful attempt to start the auxiliary power unit (APU). Garuda Indonesia Flight 421 was a scheduled domestic flight operated by Indonesian flag carrier Garuda Indonesia travelling about 625 km (388 mi; 337 nmi) from Ampenan to Yogyakarta. The clearer area was in side the Military Restricted Area, which could be entered in certain situations by obtaining permission which should be established between the relevant authorities. Then there is enough reserve for 3 restarts and faulty battery cell units… On January 16, 2002, at approximately 09:24 UTC, Garuda Indonesia flight GA421 , a Boeing 737-300, PK-GWA, ditched into the waters of the Bengawan Solo River, Central Java during a forced landing, following loss of power on both engines as the aircraft was descending through 19,000 ft. The aircraft descended into VMC conditions at about 8,000 ft altitude. My note: of all contingencies I find the 24 Volt battery incredibly the WEAKEST link of all. The letter from the NTSB also recommends to the FAA that pilots be advised to maintain a higher engine power level in moderate to severe precipitation to avoid flameout. Uninjured passengers and their personal belongings were temporarily sheltered in a nearby empty house, while injured passengers were transported by an available vehicle to the nearest clinic. Two flight attendants were found with severe injuries after the cabin floor ripped away after the tail impacted the water. Shortly after the aircraft entered the area covered by Cumulonimbus cells, the crew noted severe turbulence and heavy precipitation. The APU, electrical components and battery tests confirmed that the complete power loss following the APU start attempt was due to battery inability to maintain sufficient power. Sheer good fortune indeed. Similar occurrence happened on 24 May 1988. Only two doors were available for evacuation. One of the flight attendants didn’t survive.

By Editor • Jul 12, 2016 • 4 comments. They became VMC with the ground in sight just in time before they lost the standby ADI still in IMC. The crew tried unsuccessfully to restart the engines two or three times. Privacy, Cookies Policy, Terms and Conditions. As far as the actual emergency ditching goes, it was performed very well. Intense noise audible in data from the cockpit voice recorder as well as damage to the nose radome and engines indicate the presence of hail with the rain. The level of electrolyte in the one of the cells (i.e. Both were found with severe injuries in the river behind the aircraft, and one did not survive. Because if there is one vital lesson that should be learned from the Garuda 737 accident it is pilots must undergo regular training in the simulator for such an event. First Officer Gunawan had 7,137 flight hours.[2]:4–5. TACA Flight 110 Bengawan Solo River (Boeing 737-3T0) suffered double engine flameout while descending in heavy precipitation with engines at flight idle. The aircraft was written off as a total loss, making the accident the 11th hull loss and eighth fatal accident involving the Boeing 737-300. As the airplane descended below an overcast cloud layer at about 8,000 ft, the crew observed the Bengawan Solo River and decided to attempt to ditch the airplane into the river with flaps and landing gear retracted. The aircraft ditched in a shallow river, impacting the riverbed. One cabin crew fatally injured on forced landing impact; as a result break-off to the lower structure, including both rear lavatories, which were lost by the river stream. Residents of nearby villages assisted. However, the battery on the stricken aircraft was found to have been faulty, holding only 22 volts before the flameout occurred when a fully charged battery should have 24 volts. Had the crew manipulated the radar tilt to sweep the ground during descent, they would have been aware of the risks associated with the chosen flight path. The fact that the battery was faulty before the flameout meant the pilots’ futile attempts to restart the engines all but drained the remaining power from an already damaged battery, resulting in there being no power to start the auxiliary power unit, which explains the total loss of electrical power, even after the plane left the storm. The missing sensor was due to corrosion and not by mechanical impact. There was no fire. As the aircraft descended through the lower layer of clouds at approximately 8,000 ft (2,400 m), the pilots saw the Bengawan Solo River and decided to attempt to ditch in the river with the flaps and gear retracted. Aircraft damage: Damaged beyond repair. The Boeing 737-3Q8 was carrying 54 passengers & 6 crew members. Twelve passengers suffered injuries, while the flight crew and other two flight attendants were injured. There was simply no power to restart the engines or start the APU. Following these incidents OMB 88-5 and AD 6-14-88 were issued to require minimum rpm of 45% and to restrict the use of autothrust in moderate/heavy precipitation; engine modification was provided for increased capacity of water ingestion. Location: 22,5 km (14.1 mls) W of Yokyakarta ( Indonesia) Phase: Then the Pilot Flying requested to BALI ATC to descend to FL 190 and was cleared by Semarang APP at 09.13 UTC. The crew of Garuda Indonesia flight GA421 stated that they observed cumulonimbus cloud formations on their weather radar. Garuda Indonesia Flight 421 departed Selaparang Airport at around 15:00 and climbed to the cruising altitude of 31,000 ft. During the initial descent, the crew decided to deviate from the planned route because of thunderstorms along their planned route. I think Boeing forgot to upgrade the Battery requirements with the increased power of the engines over the years…, Also, when they started the APU and tried to restart the engines, they only waited 1 min. Aircraft speed of 290 – 295 knots was above the recommended Turbulence Penetration Airspeed of 280 knots.”, During the second attempt relight, the aircraft suffered.
