What was found
CABIN FLOOR SKIN AT THE CABIN ENTRANCE IS TOO THIN AND FLEXIBLE. THE SKIN FLEXES OVER A BULKHEAD THAT IS CENTERED IN THE ENTRANCEWAY. A BOARDING PERSON WILL PLACE THERE FEET ON EITHER SIDE OF THIS BULKHEAD. THIS CONSTANT FLEXING WOULD EVENTUALLY CRACK THE FLANGE OF THE BULKHEAD AND / OR THE FLOOR SKIN. WORKING WITH TECH REP, WE HAVE INSTALLED A HEAVY SKIN DOUBLER TO PREVENT FLEXING.
