How a “simple” maintenance error has catastrophic consequences (and another reminder on the importance of pre-flight checks) August 26 2003: a Colgan Air Beechcraft 1900 crashes off Massachusetts (US); the 2 aboard die. The plane went down shortly after taking off for a ferry flight. Aircraft had been undergoing...

49 years ago today: America´s worst air disaster May 25 1979: American Airlines Flight 191, a DC-10, crashes on takeoff from O'Hare (Chicago, US). All 271 aboard plus 2 on the ground die, the deadliest airliner crash in US, a figure only surpassed by the 9/11 terrorist attacks. On take-off, the engine separated from the wing due to improper maintenance, damaging hydraulics, and causing loss of control, as detailed below. Specifically, it was determined that during takeoff rotation, the No. 1 (left) engine separated from the left wing, flipped over the wing, and landed on the runway. The separation severed the hydraulic lines that lock the leading-edge slats in place and damaged a 3-foot (1 m) section of the left wing’s leading edge. Aerodynamic forces then caused an uncommanded retraction of the outboard slats. As the aircraft climbed, the damaged left wing generated substantially less lift than the right wing, whose slats remained deployed, and the engine provided full takeoff thrust. The resulting aerodynamic imbalance produced an abrupt left roll to a 112° bank angle—partially inverted—before the aircraft crashed in an open field adjacent to a trailer park near the runway’s end. The engine separation was caused by structural damage to the pylon, resulting from improper maintenance procedures at American Airlines, which are detailed in the thread below 1/6 ⬇️ 🧵 Video – Plane N´ Boom (animation from Mayday ACI series)

One of the most bizarre — and deadliest — plane crashes in history occurred 46 years ago: Saudia Flight 163. All 301 people on board perished, and the accident still ranks as the sixth-worst disaster in civil aviation. Why "bizarre"? Well, picture a jetliner that catches fire shortly after takeoff, returns to the airport with no major structural damage… and yet no one survives. That’s exactly what unfolded when Saudia Flight 163 landed in Riyadh, Saudi Arabia, on the night of August 19, 1980. After touching down, the pilots failed to perform an emergency stop. So, the burning aircraft continued its landing roll for nearly two miles, with fire trucks trailing behind in a surreal procession. The problems went beyond the flight crew´s actions. Airport firefighters had never been trained to open the doors of the Lockheed TriStar—even though the aircraft was part of the national airline’s fleet and operated frequently from that runway. They also didn’t know the correct emergency radio frequencies. For reasons that were never fully explained, the crew did not evacuate the plane. Looking at their qualifications makes the mystery less surprising: the captain was described as a slow learner, the first officer had previously been expelled from flight school (and later reinstated), and one crew member—who had paid for his own training—left the cockpit during the emergency, checked the cabin, and returned to report that “everything was fine” despite the fire raging inside. Passenger jets are certified to be evacuated in 90 seconds. It took firefighters 26 minutes to open the doors. By then, all 301 occupants were dead—not from burns, but from smoke inhalation. The cockpit crew didn´t even manage to leave their seats. So, calling Saudia 163 a “bizarre scenario” is no overstatement... Years later, August 19 would again make history as a dark date for aviation, by the deadliest helicopter disaster in history (albeit in combat): more details on this and others on the thread below thread 1/7 ⬇️🧵

Staines air disaster was 54 years ago June 18 1972 - BEA Flight 548, a Trident, crashes in Staines (England). All 118 aboard die, the worst air disaster in the UK. After takeoff, lift devices were prematurely retracted, inducing a superstall and loss of control. Factors: crew actions, F/O inexperience, Captain´s heart issues. The accident occurred as the aircraft entered a deep stall during the third minute of flight, and descended steeply before crashing into the ground, narrowly missing a busy main road. The public inquiry primarily attributed the accident to the captain’s failure to maintain adequate air speed and to correctly configure the high-lift devices. It also cited the captain’s undiagnosed heart condition, the co-pilot’s limited experience, and an unspecified technical issue that the crew had apparently resolved before takeoff. The accident occurred amid an impending pilots’ strike that had strained relations between crew members. The strike had also disrupted services, resulting in Flight 548 being loaded to its maximum allowable weight. The inquiry’s recommendations led to the mandatory installation of cockpit voice recorders (CVRs) in British-registered airliners. It also recommended greater caution before permitting off-duty crew members to occupy flight deck seats. Some observers considered the inquiry to be unduly biased in favour of the aircraft manufacturer. More details on thread 🧵 ⬇️ 1/7
