Does it sound like one of em Shaheed drones?
Ram air turbine deployed? Dual engine failure? |

Highly likely pilot error. The inexperienced co pilot was supposed to retract the gear but he instead retracted the flaps . If you see the cockpit layout of the 787, the flap lever is nearer to the copilot seat while the gear lever is on the captain side.

But yea, investigators have the FDR so very soon we will know...flap settings, engine performance...etc... |

If true its a very stupid and costly mistakeThe levers are so different and obvious Its like mistake handbrake for gearshift |

QUOTE(ZeneticX @ Jun 14 2025, 02:24 PM) There's a system in the 787 that prevents you from retracting the flaps until a certain altitude as well Yup, that's rightSo yeah Kevin talking out of his ass again QUOTE The Boeing 787 utilizes several mechanisms to prevent accidental flap lever movement, primarily through interlocks and electronic controls to ensure proper flap deployment and prevent inadvertent retraction, particularly during takeoff and landing. These mechanisms include physical detents on the flap lever and electronic monitoring systems that trigger alerts and potentially disengage the flap drive system if an issue is detected. Here's a more detailed explanation: Flap Lever Detents: The flap lever is designed with specific detents or notches that correspond to different flap settings (e.g., takeoff, landing, cruise). These detents provide a physical resistance, making it harder to move the lever accidentally into an undesired position. Electronic Monitoring: The flight control electronics system monitors the flap lever position and compares it to the aircraft's speed, altitude, and other relevant parameters. Asymmetry Detection: If a flap asymmetry (where one flap is in a different position than the other) is detected, the system can shut down the flap drive system and trigger an alert in the cockpit. Ground Proximity Warning System (GPWS): The GPWS may be set to "flap override" to prevent nuisance warnings during the approach if the flaps are not in the exact position expected by the system. This helps avoid unnecessary alerts when the flaps are being deployed or retracted. Interlocks: In certain configurations, the landing gear and flap levers may be interlocked, preventing the flap lever from being moved until the landing gear is down and locked, or vice versa. This prevents the flaps from being retracted prematurely or the landing gear from being raised with flaps extended. Hydraulic Control: The flap position is controlled by a hydraulic motor that is activated by signals from the flight control computer, which also monitors the flap position. Warning Systems: Various warning systems are in place to alert the crew to any malfunctions or incorrect flap settings, including visual and aural warnings. Flight Control Computer: The flight control computer is programmed to operate the flaps based on various inputs, including the flap lever position, airspeed, and altitude. Flap Asymmetry Detection: The flight control electronics cabinets are designed to detect flap asymmetry and send an EICAS (Engine-Indicating and Crew-Alerting System) message to the crew if asymmetry is detected.

Fyi, ....... https://www.aeroinside.com/aircraft-type/b7...87-8-dreamliner - Air safety incidents for Boeing 787-8 Dreamliner = nearly every month, got 1 or 2 safety incidents. Eg ....... American B788 at Miami on Mar 28th 2025, gear problem on departure Last Update: March 30, 2025 / 19:20:16 GMT/Zulu time American B788 at Miami on Nov 6th 2024, gear door problem (on departure) Last Update: November 13, 2024 / 20:39:12 GMT/Zulu time American B788 at Amsterdam on Jan 7th 2025, flap problem on departure Last Update: January 9, 2025 / 17:17:56 GMT/Zulu time Also, Ahmedabad afternoon temperature is around 40*C in June/summer = poorer flight performance. ....... https://www.businesstoday.in/india/story/ai...0262-2025-06-13 - Air India crash: Flight AI171 flew with extended gear, retracted flaps; Experts analyse what went wrong According to early visual analysis, the Dreamliner failed to follow normal flight configuration shortly after liftoff - Jun 13, 2025 10:08 AM IST .... In this case, visuals showed the gear beginning to retract but quickly extending again, possibly in reaction to an unexpected loss of thrust or a power issue. Experts point to two possible scenarios: either a mechanical or hydraulic failure that kept the landing gear stuck in the down position, or a crew decision to retract the flaps prematurely to offset drag caused by the extended gear. Both situations are highly risky, especially at low altitude and speed, where premature flap retraction could drastically reduce lift and raise the risk of a stall. ... Why the landing gear not retracted when the airplane had reached 600 feet after takeoff, before it gradually lost altitude until crashing on the ground.??? .
