The Administrator may amend any operations specifications issued under this part if—

The Administrator determines that safety in air commerce and the public interest require the amendment; or

The certificate holder applies for the amendment, and the Administrator determines that safety in air commerce and the public interest allows the amendment.

Except as provided in paragraph (e) of this section, when the Administrator initiates an amendment to a certificate holder's operations specifications, the following procedure applies:

The responsible Flight Standards office notifies the certificate holder in writing of the proposed amendment.

The responsible Flight Standards office sets a reasonable period (but not less than 7 days) within which the certificate holder may submit written information, views, and arguments on the amendment.

After considering all material presented, the responsible Flight Standards office notifies the certificate holder of—

The adoption of the proposed amendment;

The partial adoption of the proposed amendment; or

The withdrawal of the proposed amendment.

If the responsible Flight Standards office issues an amendment to the operations specifications, it becomes effective not less than 30 days after the certificate holder receives notice of it unless—

The responsible Flight Standards office finds under paragraph (e) of this section that there is an emergency requiring immediate action with respect to safety in air commerce; or

The certificate holder petitions for reconsideration of the amendment under paragraph (d) of this section.

When the certificate holder applies for an amendment to its operations specifications, the following procedure applies:

The certificate holder must file an application to amend its operations specifications—

At least 90 days before the date proposed by the applicant for the amendment to become effective, unless a shorter time is approved, in cases of mergers; acquisitions of airline operational assets that require an additional showing of safety (e.g., proving tests); changes in the kind of operation as defined in § 110.2; resumption of operations following a suspension of operations as a result of bankruptcy actions; or the initial introduction of aircraft not before proven for use in air carrier or commercial operator operations.

At least 15 days before the date proposed by the applicant for the amendment to become effective in all other cases.

The application must be submitted to the responsible Flight Standards office in a form and manner prescribed by the Administrator.

After considering all material presented, the responsible Flight Standards office notifies the certificate holder of—

The adoption of the applied for amendment;

The partial adoption of the applied for amendment; or

The denial of the applied for amendment. The certificate holder may petition for reconsideration of a denial under paragraph (d) of this section.

If the responsible Flight Standards office approves the amendment, following coordination with the certificate holder regarding its implementation, the amendment is effective on the date the Administrator approves it.

When a certificate holder seeks reconsideration of a decision from the responsible Flight Standards office concerning the amendment of operations specifications, the following procedure applies:

The certificate holder must petition for reconsideration of that decision within 30 days of the date that the certificate holder receives a notice of denial of the amendment to its operations specifications, or of the date it receives notice of an FAA-initiated amendment to its operations specifications, whichever circumstance applies.

The certificate holder must address its petition to the Executive Director, Flight Standards Service.

A petition for reconsideration, if filed within the 30-day period, suspends the effectiveness of any amendment issued by the responsible Flight Standards office unless the responsible Flight Standards office has found, under paragraph (e) of this section, that an emergency exists requiring immediate action with respect to safety in air transportation or air commerce.

If a petition for reconsideration is not filed within 30 days, the procedures of paragraph (c) of this section apply.

If the responsible Flight Standards office finds that an emergency exists requiring immediate action with respect to safety in air commerce or air transportation that makes the procedures set out in this section impracticable or contrary to the public interest:

The responsible Flight Standards office amends the operations specifications and makes the amendment effective on the day the certificate holder receives notice of it.

In the notice to the certificate holder, the responsible Flight Standards office articulates the reasons for its finding that an emergency exists requiring immediate action with respect to safety in air transportation or air commerce or that makes it impracticable or contrary to the public interest to stay the effectiveness of the amendment.
