To preclude shorting of the generator output leads at the air conditioner pulley housing and/or the oil line coupling nut, accomplish the following:
A) Within the next 10 hours' time in service after the effective date of this AD, unless previously accomplished, visually inspect the generator output leads for chafing or discoloration in the area of the air conditioner compressor pulley housing and oil line coupling nut or for positive clearance of these components, in the engine compartment:
1) If chafing has occurred, prior to further flight, comply with Paragraph B.
2) If chafing has not occurred but positive clearance does not exist between the generator leads and the air conditioner pulley housing and the oil line coupling nut, reinspect every 25 hours' time in service until Paragraph B is accomplished.
3) If positive clearance exists between the generator leads and the air conditioner pulley housing and oil line coupling nut, reinspection is not required.
B) Within the next 100 hours' time in service after the effective date of this AD or as required by Paragraph A, modify the generator lead routing in accordance with Beechcraft Service Instruction No. 0768-358/Kit No. 101-3011-1S or later approved revisions. Upon compliance with this Paragraph the inspections in Paragraph A are no longer required.
