REGULATORY TEXT:  
80-19-10 CESSNA: Amendment 39-3922. Applies to Model 335 (Serial Numbers 335-0001 thru 335-0054 and 335-0056) and Model 340A (Serial Numbers 340A0901 thru 340A0994 and 340A1002) airplanes certified in all categories.

COMPLIANCE: Required as indicated unless the requirements of Paragraph B) have been previously accomplished.

To prevent flight in adverse weather conditions with no means to supply electrical power to the deicer systems:

A) Prior to further flight:

1. Install, and operate the airplane in accordance with, a temporary placard on the instrument panel just below the glareshield in the pilot's line of forward vision when seated in the left control seat which states, "Not Approved For Flight In Icing Conditions."

2. Install black electrician's tape or equivalent over the bottom portion of the airplane Operational Limits placard, which is located on the pilot's sun visor, to cover the wording "AND FLIGHTS INTO ICING CONDITIONS IF THE PROPER OPTIONAL EQUIPMENT IS INSTALLED AND OPERATIONAL."

3. Pull the propeller deice and optional heated windshield circuit breakers, if installed, and install a band around each breaker to prevent activating those circuits.

B) Within 25 hours time-in-service after the effective date of the AD, perform the wiring inspection and accomplish the wiring change, if required, in accordance with Cessna Multi-engine Customer Care Service Information Letter ME80-31 dated July 18,1980. Make the prescribed entry in the airplane maintenance records.

C) Remove the temporary placard, cover tape and circuit breaker bands specified in Paragraphs A)1., 2., and 3. when Paragraph B has been accomplished.

D) Within seven days notify, in writing, the Chief, Aircraft Certification Program, Federal Aviation Administration, Room 238, Terminal Building No. 2299, Mid-Continent Airport, Wichita, Kansas 67209 of any incorrect wiring of the deicer buss found when complying with Paragraph B). One acceptable means of making these reports is Malfunction or Defect Report (FAA Form 8010-4). (Reporting approved by the Office of Management and Budget under OMB No. 04-R0174.) Failure to comply with this paragraph subjects owners/operators to agency enforcement action.

E) The airplane may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished.

F) Any equivalent method of compliance with this Airworthiness Directive must be approved by the Chief, Aircraft Certification Program, Federal Aviation Administration, Room 238, Terminal Building No. 2299, Mid-Continent Airport, Wichita, Kansas 67209.

This amendment becomes effective on September 29, 1980, to all persons except those to whom it has already been made effective by an airmail letter from the FAA dated September 4, 1980, and is identified as AD 80-19-10.
