Narrative:
MASwings flight MH3622, a DHC-6-400 Twin Otter, suffered a runway excursion on landing at Long Seridan Airport, Malaysia.
The aircraft came to rest in a ditch parallel to the runway.


Causes/Contributing Factors
The serious incident was caused by the aircraft wheels hydroplaning during landing on the wet and poorly maintained runway pavement. The poorly maintained runway pavement over a period of time resulted in poor surface friction qualities. The
poor mean texture depth of the aggregate and the various type of pavement distresses occurring had drastically reduced the skid resistance characteristics of the runway pavement and the braking efficiency the aircraft. The braking actions by the pilot to maintain directional control when the wheels hydroplane further aggravated the situation.
The contributing factors to this incident are poor runway maintenance practices by the aerodrome operator and pilot not adhering to the braking technique as stated in the SOP DHC6 for adverse weather operations.
