ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 82-20-02 EMBRAER: Amendment 39-4465. Applies to Models EMB-110P1 and EMB-110P2 (S/Ns 110001 through 110415) airplanes equipped with pneumatic deicing systems certificated in any category. COMPLIANCE: Required as indicated unless previously accomplished. To prevent loss of control of the airplane during approach and landing in icing conditions, accomplish the following: a) Within the next 25 hours time-in-service after July 29, 1982, on airplanes not in compliance with AD 82-15-06 or modified in accordance with paragraph b) of this AD: 1) Incorporate a temporary POH/AFM revision (immediately following page 2-10) in the affected airplane POH/AFM. This revision is set forth in Figure I of this AD. 2) Make the following pen and ink changes in the Log of Revisions, page IX, of the POH/AFM: "Temporary Revision No. 1," "add page 2-10A," "include temporary landing flap limitations" and "in accordance with Airworthiness Directive 82-15-06." 3) The incorporation of the temporary POH/AFM revision and Log of Revisions entry required by this AD may be accomplished by the owner/operator of the airplane. This person must make the prescribed entry in the aircraft maintenance records, indicating compliance with paragraph a) of this AD. b) On or before December 31, 1982: 1) Modify the horizontal stabilizer pneumatic deicing system tubing, including the relocation of the pressure switch and associated cabling, in accordance with EMBRAER Service Bulletin No. 110-30-013, March 23, 1982. 2) Provide inspection openings in the empennage in accordance with Part I of EMBRAER Service Bulletin No. 110-55-020, Change No. 1, April 22, 1982. 3) Replace pneumatic supply hoses, P/N 121-770-21-19, with new hoses, P/N B118-1, in accordance with EMBRAER Service Bulletin No. 110-30-012, March 15, 1982. 4) Upon completion of the above modifications, test the system according to procedures outlined in EMBRAER Maintenance Manual T.O. 1C95-2-6, assuring that there are no leaks. 5) If installed, remove the temporary revision to the Pilot's Operating Handbook and Centro Technico Aeroespacial (CTA) Approved Airplane Flight Manual (POH/AFM), which was installed according to AD 82-15-06. c) Aircraft may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished. d) An equivalent method of compliance with this AD may be used if approved by the Chief, Atlanta Aircraft Certification Office, FAA, P.O. Box 20636, Atlanta, Georgia 30320. This amendment supersedes AD 82-15-06, Amendment 39-4421 (47 FR 32064), effective July 29, 1982. This amendment becomes effective on September 30, 1982.

If it is suspected that ice has not been removed, or it is not possible to perform the visual check, observe the following wing flap deflection limitation: "DO NOT EXTEND THE WING FLAPS MORE THAN 50 PERCENT FOR LANDING. USE THE APPROACH SPEEDS FOR THE APPROPRIATE FLAP SETTING IN THE PILOT OPERATING HANDBOOK AND CTA APPROVED AIRPLANE FLIGHT MANUAL." LANDING DISTANCE FACTOR LIMITATIONS When using 50 percent or less wing flap deflection for landing, the landing distances given for 100 percent flap deflection must be multiplied by the following factors depending on landing weight: FOR 50 PERCENT FLAPS LANDING WEIGHT FACTOR 12,500 lbs. 1.25 11,800 lbs. 1.25 9,450 lbs. 1.00 FOR 0 PERCENT AND 25 PERCENT FLAPS LANDING WEIGHT FACTOR 12,500 lbs. 1.31 11,800 lbs. 1.31 9,000 lbs. 1.00 The above factors vary linearly between the weights given.
