47-07-02 FAIRCHILD: (Was Service Note 3 of AD-724-2.) Applies to M-62 Series Aircraft.
At each periodic inspection, determine if any looseness exists in elevator hinge attachments to rear spar of stabilizer. All loose hinges should be tightened. This will necessitate cutting oval shaped openings in the lower surface of the stabilizer just forward of the rear spar. After nuts are drawn up and safetied the openings should be covered with fabric patches.
(Fairchild Service Bulletin 44-2-C dated January 14, 1944, covers this same subject.)
