Taiwan's Aviation Safety Council (ASC) has issued several recommendations to Mandarin Airlines and the country's Civil Aeronautics Administration (CAA) following an investigation into an accident in 2012 in which an Embraer E-190 aircraft suffered damage during landing.
The accident occurred on 17 August 2012 when the aircraft, registration B-16825, was operating flight AE369 from Taipei Songshan to Makong on the island of Penghu with six crew and 104 passengers. During landing, the aircraft suffered an excursion from the runway, which was wet, damaging the aircraft's front landing gear and fuselage skins.
There were no injuries or fatalities.
According to the report, the crew flared the aircraft too early when on short final, and were slow to move the throttle to the 'idle' position. In addition, they had the flaps configured in the 'Flaps-5' position - although the E-190 manual calls for "Flaps Full" when landing on a wet or short runway. The report also faulted the crew's failure to add power and perform a go around even after they made runway contact beyond the optimum touchdown zone.
After touch down, the crew failed to "apply the best deceleration procedures" and the aircraft hydroplaned, says the report. The crew's response was to guide the aircraft off the runway into the grass. This damaged the forward landing gear and fuselage skin.
The ASC report takes particularly issue with the Mandarin Airlines' E-190 operating manual, which apparently fails to provide procedures for landing on wet or slippery runways. The manual also fails to include the standard call out for the flight crew to use when the aircraft deviates "from normal operating range."
The ASC's safety recommendations to the carrier include improved training for landings in unusual conditions, better call outs for when the aircraft encounters problems, and recommending crews to use 'Flaps Full' configuration during landings on wet or short runways.
Its recommendations for Taiwan's CAA include making sure Mandarin Airlines follows the recommendations in the report, and also ensuring that runways at Taiwan's airports are up to ICAO standards.
According to Flightglobal's Ascend Online Fleets database, the manufacturer's serial number for B-16825 is 19000167 and it is owned by GECAS. After extensive repairs, the aircraft returned to service on 18 April 2013.
Mandarin operates eight E-190s.
