ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 77-04-05 CESSNA: Amendment 39-2838. Applies to 180 Series (Serial Numbers 18050662 thru 18052711); 182 Series (Serial Numbers 18251557 thru 18264790); 185 Series (Serial Numbers 18500001 thru 18501832); 188 Series (Serial Numbers 18800001 thru 18802348); and A188 Series (Serial Numbers 18800001 thru 18800707) airplanes. Compliance: Required as indicated, unless already accomplished. To prevent ingestion of the induction air box seal into the carburetor, within the next 50 hours' time in service after the effective date of this AD, accomplish the following: A. Disconnect the carburetor air intake flexible duct assembly from the induction air box. B. Visually inspect the condition of the existing carburetor induction air box seal(s) and if not securely bonded to the carburetor intake flexible duct assembly, remove the existing seal(s) and install new P/N 0752016-10 and -11 seals in accordance with the following procedure: 1. Clean the metal surface of the carburetor air intake flexible duct assembly and the new P/N 0752016-10 and -11 seals with methyl ethyl keytone, methyl iso butyl keytone, acetone or lacquer thinner solvent. 2. Apply EC 847 adhesive to the carburetor air intake flexible duct assembly adapter and P/N 0752016-10 and -11 seals, allow to dry until tacky (usually between 5 and 30 minutes), and then press firmly together to insure contact (complete cure will occur within 24 hours). 3. Install the lower P/N 0752016-10 seal on the horizontal flat surface on the bottom side of the adapter flange, locating the forward edge of the seal so that it does not extend into the bend radius on the front side of the horizontal surface. 4. Pierce a hole in each P/N 0752016-11 seal to match the holes for the fasteners in the carburetor air intake flexible duct assembly adapter flange. 5. Reinstall the carburetor air intake flexible duct assembly flange to the carburetor induction air box. C. Any equivalent method of compliance with this AD must be approved by the Chief, Engineering and Manufacturing Branch, FAA, Central Region. Cessna Service Letter SE76-18, dated October 11, 1976, or later approved revisions, covers the subject matter of this AD. This amendment becomes effective March 1, 1977. FOOTER:
