                     TITLE 14--AERONAUTICS AND SPACE
 
CHAPTER I--FEDERAL AVIATION ADMINISTRATION, DEPARTMENT OF TRANSPORTATION 
                               (CONTINUED)
 
 PART 125_CERTIFICATION AND OPERATIONS: AIRPLANES HAVING A SEATING CAPACITY OF 
 
              Subpart E_Special Airworthiness Requirements
 
Sec. 125.111  General.


    (a) Except as provided in paragraph (b) of this section, no 
certificate holder may use an airplane powered by airplane engines rated 
at more than 600 horsepower each for maximum continuous operation unless 
that airplane meets the requirements of Sec. Sec. 125.113 through 
125.181.
    (b) If the Administrator determines that, for a particular model of 
airplane used in cargo service, literal compliance with any requirement 
under paragraph (a) of this section would be extremely difficult and 
that compliance would not contribute materially to the objective sought, 
the Administrator may require compliance with only those requirements 
that are necessary to accomplish the basic objectives of this part.
    (c) This section does not apply to any airplane certificated under--
    (1) Part 4b of the Civil Air Regulations in effect after October 31, 
1946;
    (2) Part 25 of this chapter; or
    (3) Special Civil Air Regulation 422, 422A, or 422B.
