H-60: Eyebolts Matter for Cabin Maintenance Crane

H-60 cabin maintenance crane


When there is no overhead hangar crane available to lift heavy components from an aircraft, the next best thing is your aircraft’s cabin maintenance crane. It’s a part of the UH-60 special tools test equipment covered by SC 9999-01-SKO.

When preparing the crane for use, follow the steps in the Cabin Maintenance Crane section of the current TM 1-1520-237-23&P in IETM EM 0013. One of the first tasks is to verify that the first generation eyebolts, PNs 70209-02136-102 or 70209-02136-104, are not installed on the aircraft.
These eyebolts are made of standard steel. If you operate the crane with these eyebolts, they may not hold up under the weight of the crane. That can lead to severe crane damage!

The correct eyebolts come with NSN 5306-01-337-0824 (PN 70219-02136-102). They’re listed in the Repair Parts and Special Tools section under the Structural Assembly Upper Fuselage of TM 1-1520-237-23&P. These eyebolts are made of stronger steel to accommodate the weight of the crane and the item being removed from the aircraft.

Make a note that once a year the cabin maintenance crane must be installed on an aircraft and load tested. This is best done during annual services when the air inlets are already removed.
