Narrative:A Mandarin Airlines Embraer ERJ-190, registration B-16825, sustained substantial damage in a runway excursion accident at Magong (also known as Makung), Taiwan.
Flight 369 departed Taipei-Sung Shan on a domestic service to Magong. The flight was cleared to land on runway 20. Runway length available on that runway was 6890 feet and the surface was wet. The airplane crossed the runway threshold at an altitude of about 22 feet. It descended slowly, touching down on the main wheels at 2830 feet past the runway threshold. The flight crew felt that the deceleration was not what they expected and intentionally steered the plane to the left side of the runway. Just prior to reaching the runway end, they steered the plane onto the grass. The nose landing gear was ruptured and fuselage skin was damaged due to colliding with the concrete base of four taxiway lights.
Probable Cause:
Findings related to probable causes:
During landing phase, the flight crew early flare the aircraft, did not timely retract the thrust lever to idle position. The flight crew continued holding to the control column and did not initiate a go around or reject landing after the aircraft landed beyond the touchdown zone. After landing, the flight crew did not apply the best deceleration procedures, incorrectly considered the aircraft encountered hydroplaning and intentionally controlled the aircraft out of the runway to the grass field when approaching the end of runway. The aircraft hit the handholds of the taxiway edge lights during landing roll and damaged the nose landing gear.

Follow-up / safety actions
ASC issued 7 Safety Recommendations
Issued: 12-SEP-2013 | To: Mandarin Airlines | ASC-ASR-13-09-001 |
Enhance flight crew training on operation, judgment and response to follow the procedures recommended in the manual during landing phase in different condition. |
Issued: 12-SEP-2013 | To: Mandarin Airlines | ASC-ASR-13-09-002 |
Consider to revise standard call out in relevant manual whenever aircraft deviating from normal operation range. |
Issued: 12-SEP-2013 | To: Mandarin Airlines | ASC-ASR-13-09-003 |
Recommend flight crew to choose full flap configuration during wet, heavy weight/short runway landing as the manual recommended. |
Issued: 12-SEP-2013 | To: Mandarin Airlines | ASC-ASR-13-09-004 |
Recommended operator to acquired sufficient landing performance data, such as landing distance at wet runways or other performance data that may affect landing distance condition, consider the actual landing distance to reflect the operators specific operational practices, procedures, training and experience and provide the extra 15% safety margin landing distance data for flight crews reference during approach. |
Issued: 12-SEP-2013 | To: CAA Taiwan | ASC-ASR-13-09-005 |
Supervise Mandarin Airlines to add extra 15% safety margin landing distance data for flight crews reference during approach; Supervise Mandarin Airlines to revise standard call out in relevant manual whenever aircraft deviating from normal operation range; Supervise Mandarin Airlines to enhance flight crew flare operation during landing phase, enhance flight crews judgment and response training. Supervised Mandarin Airlines flight crew adhere to procedure as the manual recommended to choose full flap configuration during wet, heavy weight /short runway landing in different condition. |
Issued: 12-SEP-2013 | To: CAA Taiwan | ASC-ASR-13-09-006 |
Examine all national airports followed ICAO ANNEX 14 and Civil Aerodrome Design and Operation Standards to adopt measures to prevent aircraft from hitting the hard vertical surface of any objects within runway area when aircraft wheels sink in the grass field. Examine ditches within a precision approach runway leveling area shall be leveled or covered to prevent aircraft damage after veering off the runway. |
Issued: 12-SEP-2013 | To: Air Force Command Headquarters | ASC-ASR-13-09-007 |
Examine all national military and civilian jointly airport to follow ICAO ANNEX 14 and Civil Aerodrome Design and Operation Standards to adopt measures to prevent an aeroplanes wheel, when sinking into the ground, from striking a hard vertical face. |
