Japan's transport ministry wants certified aircraft facilities to stop waiting on individual government sign-off for routine safety bulletins. The Ministry of Land, Infrastructure, Transport and Tourism's Civil Aviation Bureau opened public comment on August 25, 2026, on changes to six linked circulars governing how it approves "technical bulletins," the service-bulletin equivalents that manufacturers and design holders issue when an aircraft or component needs attention. Comments close September 24, 2026, and the ministry expects to issue the final rules around October 2026. The ministry frames the change as cutting bureaucratic drag as Japan's aerospace supply chain expands overseas, pointing to the improved technical capability of certified facilities as the justification for handing them more authority.
Under the draft, bulletins classified "Mandatory" would still need the bureau's direct approval before a manufacturer can issue them. But bulletins in the lower "Essential" tier could instead be cleared by the manufacturer's own certified facility, through a conformity check carried out by a designated "confirmation supervisor," provided four conditions are met: the bulletin does not require an airworthiness improvement notice (Japan's equivalent of an airworthiness directive), it is not for a major repair or modification, and it is not a foreign manufacturer's bulletin being reissued under a Japanese aircraft's name. Facilities that want to use this path must first get the ministry to approve the relevant procedures in their own operating manuals, keep signed confirmation records, and still ask the bureau case by case whether an airworthiness notice is needed before clearing anything themselves. The ministry retains the right to demand those records or order corrective steps if it judges a facility's self-check inadequate.
A second change widens a separate shortcut. Maintenance-and-inspection certified facilities already hold a "comprehensive" flight-test permit that lets them skip individual per-flight approval under Article 11 of the Civil Aeronautics Act. The draft extends that blanket permit to aircraft-manufacturing inspection facilities too, covering first-time airworthiness test flights on newly built aircraft and test flights on aircraft whose certificates have lapsed.
| Change | What it does |
|---|---|
| Technical bulletin self-certification | Certified facilities can clear "Essential" bulletins themselves if four conditions are met, instead of waiting for MLIT approval |
| Flight-test blanket permit expanded | Aircraft-manufacturing inspection facilities join maintenance facilities under the comprehensive Article 11 flight-permit system |
| Export paperwork trimmed | Aircraft built in Japan for export without Japanese registration skip registration-number and registration-certificate-copy requirements |
| Qualification reference updated | Certification-supervisor rules now cite the new "specified specialized courses" from the April 2026 School Education Act revision |
The package also trims paperwork for exporting Japanese-built aircraft that will not carry Japanese registration: applicants would no longer need to record a registration number or symbol on the airworthiness-certificate application, attach a copy of the registration certificate, or list registration details on the aircraft status form. Separately, the rules update references to certification-supervisor qualifications so they match the "specified specialized courses" created by an April 2026 revision to the School Education Act, replacing an outdated citation to the old vocational-course provision.
None of this touches the standard for Mandatory bulletins or airworthiness directives, and the ministry keeps its backstop authority intact. Public comment runs through September 24, 2026, ahead of an expected rollout around October.
