Contractor notes that A5 references WI 1005 for replacement Tie Downs.

The question was for WI 1004 Inspections.

Q 5: WI 1004 4.2 GFM only shows replacement gaskets. Does the GOV'T have spare Button Hd Monel K-500 screws if any fail during removal? Spare Recoils? Cross Bars?

This could speed up the repair process if failures are encountered.

ALL COMPONENTS WILL BE PROVIDED WITH THE NEW TIE DOWNS. THERE ARE NO SPARES

Q 6: Can the Flight Deck coating be prepared with a combination of open UHP blasting and vacuum grit blasting? Can this be accomplished prior to WIs 1004 & 1005? This could be helpful prepping the Cross Bars & Button Hd Screws for removal.

GOV'T Reply clarification request:

A6: Vendors has the option to use UHP or Vacuum blast for the flight deck preservation. Schedule of the jobs is up to vendor discretion. The tiedowns have to be covered during flight deck blasting and painting. However, if there are defects found during inspection of WI 1004, the tie downs paint will have to be removed for further inspection. If new tie downs are installed prior to flight deck removal and installation, then they will have to be covered for flight deck removal/installation. If some of the old tie downs are SAT during WI 1004 inspection, then they will have to be covered as well prior to flight deck removal/installation.
