on
Ahmedabad, India – Thursday, June 12, 2025 | 13:40 LT Tragedy struck in Ahmedabad today when Air India flight AI171, a Boeing 787-8 Dreamliner, crashed shortly after takeoff from Sardar Vallabhbhai Patel International Airport (AMD). The flight was En route to London-Gatwick Airport (LGW). According to early reports, 241 of the 242 people onboard are feared dead, with one survivor critically injured. The crash also claimed the lives of at least five people on the ground, bringing the total fatality count to 246. The aircraft, registered VT-ANB, took off from runway 23 and remained airborne for approximately 30 seconds. Eyewitnesses and videos reveal that after climbing for about 12 seconds, the aircraft began losing altitude. The landing gear was still extended during descent. The main landing gear struck the top floor of a doctor’s hostel, reportedly housing a restaurant. The tail section separated upon impact, and the fuselage continued forward before bursting into flames and crashing...

Azur Air Boeing 767 Incident Over Russia – Analysis and Updates

on

Date: Monday, December 2, 2024

Time: Approximately 09:00

Location: Over the Republic of Khakassia, Russia

Incident Overview

An Azur Air Boeing 767-306ER (Registration: RA-73034) operating as flight ZF2943 from Tomsk-Bogashevo Airport (TOF) to Phuket International Airport (HKT) encountered a serious technical malfunction en route. The aircraft, with over 300 passengers aboard, diverted to Novosibirsk International Airport (OVB) following an in-flight shutdown of its right engine.

No fatalities were reported, but the aircraft remains grounded pending an investigation. The flight crew initially reported a drop in oil pressure in the right engine after reaching cruising altitude. Shortly after, the engine shut down entirely. A PAN-PAN emergency signal was declared as the crew initiated a descent toward the alternate airport.


Technical Analysis: Potential Causes of the Incident

1. Engine Oil System Failure

A drop in oil pressure is often indicative of a problem within the lubrication system, which is critical for engine operation. Possible causes include:
  • Oil Leakage: A breach in the oil system, such as a ruptured line or faulty seal, could result in inadequate lubrication.
  • Oil Pump Malfunction: Failure of the oil pump might have led to insufficient oil delivery to engine components.
  • Sensor or Indication Fault: Although less likely given the subsequent engine shutdown, a malfunctioning sensor might have initially provided false data to the crew.

2. Component Wear and Tear

Given the aircraft’s age (manufactured in 1997), aging engine components may have played a role:

  • Bearing or Shaft Failure: Worn-out bearings or shafts might have caused overheating and subsequent failure.
  • Seal Deterioration: Over time, seals can degrade, leading to oil leaks or contamination.

3. Contamination or Blockage

Contaminants in the oil system, such as debris or sludge, can obstruct oil flow:

  • Maintenance Gaps: Inadequate or improper maintenance could result in undetected oil contamination.
  • Blocked Oil Lines or Filters: Obstructions in the oil pathways can restrict lubrication and cooling.

4. External Factors

  • Foreign Object Damage (FOD): While less likely at cruising altitude, ingestion of debris during takeoff or ascent could have initiated damage.
  • Operational Stress: Continuous high engine output during initial climb could exacerbate pre-existing vulnerabilities.
