## Discrepancy

THE ACFT LEFT WING L/E WAS DAMAGED BY A BIRDSTRIKE. THE DAMAGE WAS OUTSIDE THE GUIDANCE OF THE SRM FOR "ALLOWABLE DAMAGE".  TECHNICAL SUPPORT WAS CONTACTED, AN ENGINERING REPAIR MEMO AND "STATEMENT OF APPROVED DESIGN DATA" ECC-12-RM-11-249 WAS ISSED.  THE ACFT WAS REPAIRED USING THOSE INSTRUCTIONS, UTILIZING A FLUSH PATCH AND DOUBLERS FOR THE REPAIR OF THE EXISTING L/E SKIN AND RIBS.  AN FAA FORM 337 DATED 12-15-2011 WAS SUBMITTED.
