What was found
ACFT ARRIVED AT FACILITY WITH A REPEAT ISSUE OF DIFFICULTY LATCHING AND BENT LOWER DOOR LATCH ON THE PILOTS SIDE DOOR. REMOVED THE EXISTING LATCH AND INSTALLED A NEW LATCH, PN 28161-001 IAW ACFT MFG, AMM 52-10K, 1 & 2. WE THEN NOTICED THE DOOR REQUIRED ADJUSTMENT BASED ON THE FIT AROUND THE DOOR AND THE AIRFRAME STRUCTURE. ADJUSTED THE DOOR FOR PROPER FIT IAW AMM CHAPTER 52-10B 1, 2, AND 3D. AFTER THE ABOVE REF MAINTENANCE THE DOOR OPERATION WAS BETTER BUT THE LATCH WAS FOUND TO CONTACT THE LOWER AIRFRAME STRIKER PIN, PN 20268-003 AT THE UPPER MOST LIMIT. IN THIS CONDITION, IT IS POSSIBLE FOR THE LATCH HOOK TO BE BENT DURING CABIN DOOR CLOSING OPERATION FROM CONTACT WITH THE TOP OF THE STRIKER PIN IF NOT CAREFUL. THERE IS NO VERTICAL ADJUSTMENT TO THE LATCH OR STRIKER PIN FOR ALIGNMENT. THE IPC CALLS OUT ONLY 1 ROTARY LATCH SPACER, PN 20298-001, NOT AS REQUIRED. A FIELD SERVIE REQUEST TO ACFT MFG HAS BEEN SENT FOR DISPOSITION ON THIS MATTER.
