Overview of Rolls-Royce M250-B15G Manual
The beginning of the Rolls-Royce M250-B15G technical manual introduces a Commercial Service Letter (CSL) Index providing a structured outline of available documentation for the Rolls-Royce M250-B15G engine. This index includes revision histories, titles/descriptions, and the topical categorization of service letters intended for commercial service support. Individual CSLs encompass a broad range of subjects from maintenance center overviews to detailed part-specific directives.
Content of the CSL Index
The index details various technical publications and revisions, annotating their status (active, reissued, or cancelled) alongside a reference for additional information. Documents cover areas such as:
- Maintenance Centers Information: Identification of authorized maintenance centers, warranty details, and contact information.
- Lubrication Specifications: Recommendations on approved lubricants for the engine’s oil system, though some entries related to this have been cancelled and referred to the operations and maintenance manual.
- Parts Regulations: Insight into time-limited parts for the M250-B15G series, overhauls, fuel system components, and o-rings, with successive cancellations directing users to the primary operations and maintenance manual.
- Fuel Usage: Instructions on the proper mixtures of aviation gasoline for various operational conditions, approved fuels, and cold weather procedures, also cancelled and accompanied by referrals to the main manual.
- Component Maintenance: Guidance on inspecting components such as the starter generator, compressor washing techniques, spline wear, and drive shafts, all now referenced in the comprehensive operations manual.
- Reporting and Storage: Procedures for utilizing engine log books, reporting on engine conditions, and handling parts that may have been stored for extended periods.
Manual Structure
Each service letter is identified by a CSL number, enabling indexed referencing and streamlining the consultation process. The index supports efficient navigation, allowing service technicians and engineers to promptly locate pertinent information relevant to the operation and maintenance of the M250-B15G engine.
Note on Documentation Status
It’s important to note that several of the technical publications listed in the index have been marked as cancelled and refer the user to the corresponding sections in the operations and maintenance manual. This signals that the static CSL index is part of a dynamic documentation ecosystem that evolves to meet the latest procedural standards and regulatory requirements.
The document closes with an effective revision date of March 3, 2020, signifying the last update to the information contained within the first two pages of the manual.
