 PART 125_CERTIFICATION AND OPERATIONS: AIRPLANES HAVING A SEATING CAPACITY OF 
 
             Subpart F_Instrument and Equipment Requirements
 
Sec. 125.221  Icing conditions: Operating limitations.

    (a) No pilot may take off an airplane that has frost, ice, or snow 
adhering to any propeller, windshield, wing, stabilizing or control 
surface, to a powerplant installation, or to an airspeed, altimeter, 
rate of climb, or flight attitude instrument system, except under the 
follow conditions:
    (1) Takeoffs may be made with frost adhering to the wings, or 
stabilizing or control surfaces, if the frost has been polished to make 
it smooth.
    (2) Takeoffs may be made with frost under the wing in the area of 
the fuel tanks if authorized by the Administrator.
    (b) No certificate holder may authorize an airplane to take off and 
no pilot may take off an airplane any time conditions are such that 
frost, ice, or snow may reasonably be expected to adhere to the airplane 
unless the pilot has completed the testing required under Sec. 
125.287(a)(9) and unless one of the following requirements is met:

[[Page 1005]]

    (1) A pretakeoff contamination check, that has been established by 
the certificate holder and approved by the Administrator for the 
specific airplane type, has been completed within 5 minutes prior to 
beginning takeoff. A pretakeoff contamination check is a check to make 
sure the wings and control surfaces are free of frost, ice, or snow.
    (2) The certificate holder has an approved alternative procedure and 
under that procedure the airplane is determined to be free of frost, 
ice, or snow.
    (3) The certificate holder has an approved deicing/anti-icing 
program that complies with Sec. 121.629(c) of this chapter and the 
takeoff complies with that program.
    (c) Except for an airplane that has ice protection provisions that 
meet appendix C of this part or those for transport category airplane 
type certification, no pilot may fly--
    (1) Under IFR into known or forecast light or moderate icing 
conditions; or
    (2) Under VFR into known light or moderate icing conditions, unless 
the airplane has functioning deicing or anti-icing equipment protecting 
each propeller, windshield, wing, stabilizing or control surface, and 
each airspeed, altimeter, rate of climb, or flight attitude instrument 
system.
    (d) Except for an airplane that has ice protection provisions that 
meet appendix C of this part or those for transport category airplane 
type certification, no pilot may fly an airplane into known or forecast 
severe icing conditions.
    (e) If current weather reports and briefing information relied upon 
by the pilot in command indicate that the forecast icing condition that 
would otherwise prohibit the flight will not be encountered during the 
flight because of changed weather conditions since the forecast, the 
restrictions in paragraphs (b) and (c) of this section based on forecast 
conditions do not apply.
