Where the complaint states allegations of offenses which occurred more than 6 months prior to the Administrator's advising the respondent as to reasons for proposed action under 49 U.S.C. 44709(c), the respondent may move to dismiss such allegations as stale pursuant to the following provisions:

(a) In those cases where the complaint does not allege lack of qualification of the respondent:

(1) The Administrator shall be required to show, by reply filed within 15 days after the date of service of the respondent's motion, that good cause existed for the delay in providing such advice, or that the imposition of a sanction is warranted in the public interest, notwithstanding the delay or the reasons therefor.

(2) If the Administrator does not establish good cause for the delay, or for the imposition of a sanction in the public interest notwithstanding the delay, the law judge shall dismiss the stale allegations and proceed to adjudicate the remaining portion of the complaint, if any.

(b) In those cases where the complaint alleges lack of qualification of the respondent, the law judge shall first determine whether an issue of lack of qualification would be presented if all of the allegations, stale and timely, are assumed to be true. If so, the law judge shall deny the respondent's motion. If not, the law judge shall proceed as in paragraph (a) of this section.
