Compliance is required within the next 10 hours time in service after the effective date of this AD, unless already accomplished.

To prevent a possible turbocharger exhaust coupling failure, which could result in a fire hazard, accomplish the following:

(a) Gain access to turbocharger exhaust system.

(b) Remove the turbocharger exhaust coupling P/N 556 108 and tailpipe P/N 98705- 2.

(c) Using either a dye penetrant method or a 10-power magnifying glass, inspect coupling, coupling bolt, tailpipe and tailpipe flange for cracks, deformation or damage.

(d) Measure width across inside opening of retainer segments of coupling. Maximum allowable dimension is .350 in (See Figure 1)

(e) Measure thickness of tailpipe flange at apex. Dimension required is .096 plus or minus .005 inch. (See Figure 1)

(f) If flange dimension is under the tolerance shown in (e) above, replace tailpipe. If over tolerance, rework the flange mating surface to dimensions in (e) above, provided .005 inch flatness is maintained or replace with serviceable part.

(g) Replace any exhaust system parts found cracked, deformed or damaged during the inspection required above with a serviceable part, before further flight.

(h) Reinstall serviceable parts as follows:

(1) Assure turbocharger and tailpipe flange are properly aligned. Tap coupling gently to distribute band tension while tightening coupling nut.

(2) Torque coupling nut to 40-50 inch pounds and safety wire.

(i) Make appropriate maintenance record entry.

An equivalent method of compliance may be approved by the Chief, Engineering and Manufacturing Branch, Federal Aviation Administration, Southern Region, P.O. Box 20636, Atlanta, Georgia 30320.

This amendment is effective upon publication in the Federal Register as to all persons, except those persons to whom it was made immediately effective by priority mail, issued June 14, 1979, which contained this amendment.
