9 Irregularities

9-1 Introduction

Mail-handling irregularities are failures by air carriers to comply with Postal Service rules, regulations, and requirements related to transporting mail by aircraft. Irregularities are extremely serious. Air carriers incurring any of the irregularities defined in this chapter are subject to assessment. Continued non-compliance can result in an air carrier’s disqualification from the carriage of mail. The Postal Service strictly enforces requirements, not to penalize air carriers but rather to bring problems to the attention of the air carrier’s management so they can be resolved, thereby promoting and maintaining service goals.
