Narrative:
The Boeing 767 was approaching Cheju (CJU) and cleared to land on runway 24. Crosswind existed from 310 degrees at 22 to 24 knots. After a normal landing on the main wheels the nosewheel touched down hard. The aircraft sustained substantial damage to the fuselage with upper fuselage crown damage between stations 610 and 654. The nose wheel well bulkhead (station 287) and skin panels in fuselage section 41 were also damaged.

Follow-up / safety actions

Following this and two similar 767 accidents in 1992 and 1993, Boeing initiated production modifications to strengthen the upper crown portion of the fuselage effective on assembly line position 563. Boeing also also published landing techniques in its flight training manual, a Flight Operations Technical Bulletin on the issue and an article in the Airliner magazine.
The NTSB urged that more permanent, clear, cautionary material be added to
flight manuals and that this material be emphasized during initial and recurrent
traininig. On June 16, 1994 the NTSB issued safety recommendations A-94-118 through -121 to address this issue on 767 and other airplanes.

languages:

Issued: 16-JUN-1994	To: FAA	A-94-118
Require that all FAA-approved Boeing 757/767 Operating Manuals, and other airplane model Operating Manuals as deemed appropriate, clearly communicate derotation techniques and the potential for excessive pitch rates after touchdown if pilots use large nose-down control column deflections. Such information should be inserted in the sections of the manual that refer to normal and crosswind approach and landing, as a cautionary note. Instructions calling for positive forward control pressure after nose wheel touchdown should be replaced with a warning to smoothly fly the nose wheel to the runway by relaxing aft control column pressure and not to use full down elevator.
Issued: 16-JUN-1994	To: FAA	A-94-119
Modify initial and recurrent Boeing 757/767 pilot training programs, and other airplane model pilot training programs as deemed appropriate, to include discussion of derotation accidents.
Issued: 16-JUN-1994	To: FAA	A-94-120
Require design modification to the Boeing 757/767 so that flight control position data to the DFDR is accurate and not filtered by the EICAS. The sample rate should also be increased to an appropriate value.
Issued: 16-JUN-1994	To: FAA	A-94-121
Review other airplane designs to ensure that flight control position data to the DFDR are accurately recorded and that flight control position data filtered by systems such as EICAS are not substituted for accurate data.
