Following a hard landing, ground inspections revealed severe damage to RH engine cowling. Damage is consistent with No. 2 engine contacting the runway upon landing at speed. Damage beyond OEM SRM limits.
Following a post-flight poor performance report, detailed inspection revealed split and leaking pitot air tube at entrance to upper instrument panel. It was noted that only the portion of tube that was exposed to direct sunlight (via the front windscreen) was found to be brittle. Tube was renewed and secured to fuselage structure as to limit the exposure to sunlight as much as possible without modifying the existing design.
During accomplishment of an alert SB, forward RHS upper float fitting bolt sheared off. Bolt removed and replaced. P/No: 2219BC080038L.
During scheduled inspections, upper channel of the rudder torque tube and arm assembly was found with a minor crack in the return approximately one inch from the rudder stop striker plate. Post removal of the rudder torque and arm assembly for replacement, further inspection was carried out. The lower channel was also found cracked. Further, fitting was found cracked through longitudinally at an upper fastener hole. Attaching collar was found cracked through longitudinally from a lower fastener hole. Failure of either the rudder torque tube lower fitting or upper collar could lead to loss of control of the rudder. The rudder torque and arm assembly was replaced with a serviceable item and the aircraft returned to service.
