## The airworthiness directive

61-15-04 LOCKHEED: Amdt. 309 Part 507 Federal Register July 21, 1961. Applies to All 188 Series Aircraft Incorporating A Lounge Using Hardman Seats.

Compliance required as indicated.

Reports have been received that grommets are missing in some of the aft lounge safety belt cable guide brackets. Grommets are required in these brackets to permit the cable to withstand the design load. Within the next 100 hours' time in service inspect the safety belt cable guide bracket, Hardman P/N 5072-1, of the left and right aft lounge seats for presence of nylon grommets. If the nylon grommets are missing, install nylon grommets, P/N 295957-10A (United Carr Fastener Corp.), or equivalent, or restrict occupancy of the left and right aft lounge seats during takeoff and landing until such time as grommets are installed.

(Lockheed Service Bulletin 88/SB-541 refers to the same subject.)
