Possible Misidentification of TCM Ignition Systems (formerly Bendix) D-2000/D-2200 Dual Magnetos
Summary
The Safety Alert for Operators (SAFO) titled "Possible Misidentification of TCM Ignition Systems (formerly Bendix) D-2000/D-2200 Dual Magnetos" addresses the issue of certain TCM/Bendix D-2000 and D-2200 dual magnetos being misidentified as D-3000 magnetos. This misidentification involves the magneto housing and data plates, which may affect compliance with applicable airworthiness directives (ADs). The document is relevant to operators and maintenance personnel working with aircraft engines equipped with these specific magnetos.
What Changed
This SAFO highlights the discovery that some D-2000 magneto housings have been incorrectly labeled as D-3000, including changes such as additional distributor hold down screw holes similar to the D-3000 design. It clarifies that FAA-approved alterations allowing these changes do not serve as alternate methods of compliance, and all relevant ADs for the D-2000/D-2200 magnetos remain mandatory.
Why It Matters
Accurate identification of magnetos is critical for ensuring compliance with safety directives and preventing ignition failures or distortion issues. Misidentification can lead to improper maintenance or inspection, potentially compromising engine reliability and safety. Aviation professionals must be vigilant to verify magneto conformity beyond data plate markings to maintain airworthiness and regulatory compliance.
What To Do
Maintenance and inspection personnel should carefully verify the type design conformity of TCM/Bendix D-2000 and D-2200 dual magnetos during all servicing activities. They should not rely solely on data plate information and must ensure all applicable ADs are complied with. Any findings of noncompliance should be reported promptly to the local Flight Standards District Office.
