Aircraft Maintenance Personnel (AMP) are an important group in the aviation industry. These personnel are responsible to make sure that the aircraft are safe prior to flight. Having knowledge in aircraft technology is insufficient without an appropriate level and type of English language proficiency among the AMP. Due to this, the AMP must be able to read and understand written documentation pertaining to aircraft maintenance. This study aims to identify the communicative activities that influence or complement reading activities among the AMP. Data collection for this study involved semi-structured interviews with a total of 23 participants selected from two domain expert informant groups: (1) specialists who are ex-AMP and currently working as academic staff at a higher learning institution offering courses in aviation technology, and (2) AMP who are currently working in the aviation industry. This study found that the nature of the AMP directed to three hierarchical groups in the aircraft maintenance domain: (1) aviation authorities (ICAO) and (CAAM) ranked top of aircraft maintenance domain, (2) aircraft makers (OEM) second, and (3) end-users air operators and (MRO) organisations positioned at the lowest rung in the community. These three communities produced different types of documents which are categorized as (1) documents produced by the regulatory body, (2) documents prepared by the aircraft manufacturer, and (3) documents prepared by the aviation organization. It can also be concluded that the AMP read these documents in order is to assist them in performing aircraft maintenance tasks.
