(b) If during the inspection required by paragraph (a) of this AD, a connecting rod is found to be cracked or bowed, before further flight, except that the airplane may be flown in accordance with FAR Section 21.197 and 21.199 to a base where the repair can be performed -

(1) Replace the cracked or bowed part with a serviceable part of the
same part number or an FAA-approved equivalent part; and

(2) Comply with paragraph (e) of this AD.

(c) If during the inspection required by paragraph (a) of this AD, an indication of contact of an aileron trim tab connecting rod with the adjacent structure is found but the connecting rod is free of cracks and bowing, before further flight, except that the airplane may be flown in accordance with FAR Section 21.197 and 21.199 to a base where the repair can be performed -

(1) Restore the protective finish to all dented and chafed areas of the connecting rod, and

(2) Comply with paragraph (e) of this AD.
