Damage to the aircraft of JL 82

Outline

On March 31, 2012, JL082(Shanghai Hongqiao to Tokyo Haneda) made a Tail Strike when the aircraft was climbing up for making a Go Around at Tokyo International Airport. No injuries occurred, but due to the damage to the aircraft, the occurrence was designated an aircraft accident by the Japan Civil Aviation Bureau (JCAB) of MLIT.

Investigation into the cause

Investigations were conducted by the Japan Transport Safety Board, and results were announced on December 18, 2014. According to their report, it is highly probable that the aircraft continued rolling with pitch-up altitude after touchdown, causing the aft fuselage to come into contact with the runway and be damaged.

It is highly probable that the aircraft continued rolling with the pitch-up attitude for the following reasons; After touchdown, the Captain had felt the aircraft had bounced to the extent necessary for a go-around and decided to make a go-around to avoid a hard landing. Even after he became aware that the reverse thrust levers had been raised, he continued making a go-around.

Furthermore, it is somewhat likely that, in a situation where the Captain had been assisting the co-pilot with control and without the Captain's declaring a takeover, the Captain's intention was not properly conveyed to the co-pilot, the sharing of duties between the Captain and co-pilot became momentarily unclear, and the monitoring of flight information was not performed adequately.

Countermeasures

JAL implemented the following countermeasures after the accident.

  1. Clarified procedures when the co-pilot controls in the right seat, takeover procedures, and meteorological conditions, organized regulations and conducted collective training.
  2. Conducted training of Captains holding the company qualification of Left Approved Captain*1 using a simulator

    Reaffirm the importance of PM (pilot mainly in charge of duties other than flying) duty
    Perform and confirm appropriate takeover
    Perform a safe go-around after takeover near touchdown

    *1 A qualification to instruct a co-pilot in the right seat to operate as PF (pilot mainly in charge of flying)

  3. Precautions when operating reverse thrust levers after touchdown

Serious Incident

An incident involving circumstances indicating that there was a high probability of an accident, such as overrunning, emergency evacuation, fire or smoke inside the cabin and abnormal depressurization, encountering abnormal weather conditions, etc, as classified by the Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT).

Go Around by Japan Air Commuter Flight 3626

Outline

On May 10, 2011, Japan Air Commuter Flight 3626 (from Miyazaki to Fukuoka) received permission for landing from ATC and was approaching Fukuoka Airport when ANA Flight 487, which was scheduled to take-off from the same runway, entered the runway with permission for take-off from ATC. The JAC aircraft made sure of permission for landing with ATC, and the aircraft performed Go Around under ATC instruction. None of the passengers and crews were injured. This case was classified as a Serious Incident by MLIT.

Investigation into the cause

Investigations were conducted by Japan Transport Safety Board, and the results were announced on April 27, 2011. According to the report, the incident is said to be caused by an air traffic controller who issued take-off clearance to an ANA flight, while forgetting that he had issued landing clearance to the JAC flight.
