ROBINSON MODEL R22

VFR day and night operations are approved. VFR operation at night is permitted only when landing, navigation, instrument, and anti-collision lights are opera- tional. Orientation during night flight must be maintained by visual reference to ground objects illuminated solely by lights on the ground or adequate celestial illumination. Note: There may be additional requirements in countries outside the United States.

Flight when surface winds exceed 25 knots, including gusts, is prohibited. 2. Flight when surface wind gust spreads exceed 15 knots is prohibited. 3. Continued flight in moderate, severe, or extreme turbulence is prohibited. Adjust forward airspeed to between 60 knots indicated airspeed (KIAS) and 0.7 V ne but no lower than 57 KIAS, upon inadvertently encountering moderate, severe, or extreme turbulence. Note: Moderate turbulence is turbulence that causes: (1) changes in altitude or attitude; (2) variations in indicated airspeed; and (3) aircraft occupants to feel definite strains against seat belts. RHC NOTE This AD is issued by the FAA and is applicable to US-registered helicopters. INTENTIONALLY BLANK
