OPNAVINST 3750.6T - Naval Aviation Safety Program

Scope

OPNAVINST 3750.6T issues U.S. Navy policies, guidelines, procedures, and responsibilities for the Naval Aviation Safety Program. The instruction governs Marine Corps aviation safety as well, since Marine aviation operates under the Naval Aviation Safety umbrella. The original portal entry was filed as "MCO 3750.6" but no MCO carries the number. The "MCO 3750.6" alias preserves back-compat for any inline reference written before the renumber.

Audience

Marine aviation commanders executing the aviation safety functional area. Aviation Safety Officers (ASOs) applying MCO 5100.29C Volume 4 to Marine aviation activities in coordination with this instruction. Ground Safety Officers and Aviation Safety Enlisted Advisors appointed in writing at the squadron. S-1 sections filing the appointment letters.

Key changes in 3750.6T

• References to the Naval Safety Center (NAVSAFECEN) replaced with Naval Safety Command (NAVSAFECOM).
• The legacy WESS web safety system replaced with the Risk Management Information (RMI) program of record. RMI is the only authorized application for reporting and recording mishaps, hazards, and safety incidents in the DON.

Operative content as used in the portal

• The commander oversight matrix carries an Aviation Safety row under the "MCO 3750.6" label. Summarized commander actions. Chair the Enlisted and Aviation Safety Councils. Appoint the ASO, GSO, and ASEA in writing. The matrix marks its rows as IGMC FAC summaries pending a source-text walk.
• Aviation Safety is an IGMC CoRE+ functional area, FA number 3750.6, sponsored by HQMC (SD), with a published checklist effective 2025-04-03 per the portal FA registry.

Status

Signed 2024-10-24, superseding OPNAVINST 3750.6S. Caution. The portal commander aviation safety page anchors the Naval Aviation Safety Management System, including ASO appointment and NPS course requirements, to OPNAVINST 3750.1B, a separate instruction. This entry keeps the official 3750.6T subject. Confirm which instruction carries a given requirement before citing either one in a signed document.
