- An appropriately rated and authorized AME shall complete the TE inspection during the most frequent inspection contained in the air operator’s aircraft maintenance schedule approved in accordance with section 605.86 of the CARs.
- Main rotor blade painting as recommended in MDHI CSP-HMI-2 section 20-30-00 shall be complied with during the first scheduled inspection described in condition 7 of this exemption.
