Japan Issues Business Improvement Advisory to ANA Over Maintenance Misconduct

Japan’s transport ministry has taken formal regulatory action against All Nippon Airways (ANA) following a series of MRO lapses. On April 14, 2026, the government issued a business improvement advisory to the carrier, citing insufficient safety oversight.

As detailed by Japan Today, the advisory was triggered by two specific incidents in late 2025 involving improper conduct and falsified records by maintenance staff. Because these infractions occurred while ANA was already under a corrective mandate for a similar issue in 2024, regulators determined that the airline’s internal controls were inadequate.

In response to the government’s mandate, ANA Holdings Inc. has announced sweeping disciplinary measures. The corporate penalties will affect 50 executives, including significant pay reductions for top leadership, as the Airlines scrambles to restore public and regulatory trust.

Details of the Maintenance Misconduct

The 2025 Incidents

According to reporting from Japan Today, the transport ministry highlighted two primary violations from November 2025. On November 13 at Narita Airport, a mechanic identified damage to a cargo compartment rail but dismissed it as a minor defect without consulting safety regulations. The aircraft was cleared to fly despite the wear exceeding permissible limits.

Shortly after, on November 27 at Itami Airport, another mechanic used a prohibited type of oil while replacing a brake valve. Although the error was caught, the mechanic falsified the maintenance logs and allowed the aircraft to operate without proper corrective measures.

The 2024 Precedent

The severity of the government’s response is heavily influenced by historical context. In October 2024, a maintenance worker at Fukushima Airport failed to report and replace underinflated aircraft tires. The transport ministry issued a stern warning to ANA at that time, mandating corrective actions that were supposedly active when the 2025 incidents occurred.

Government Mandates and Corporate Accountability

Ministry Deadlines

The Ministry of Land, Infrastructure, Transport and Tourism has ordered ANA to overhaul its safety management structure. The airline is required to submit a comprehensive formal report detailing its improvement plans by May 15, 2026.

Executive Pay Cuts

To demonstrate accountability for the systemic oversight failures, ANA Holdings Inc. is penalizing 50 executives for fiscal 2025. Notably, former President Shinichi Inoue and current President Juichi Hirasawa, who served as senior executive vice president during the 2025 infractions, will both receive a one-month, 30 percent pay cut.

ANA’s Response and Corrective Measures

ANA has publicly addressed the advisory, emphasizing that neither of the November 2025 incidents ultimately compromised flight Safety. However, the carrier acknowledged the gravity of the regulatory breach.

“We take this situation very seriously… We will do our utmost to prevent a recurrence and restore trust.”

Moving forward, ANA has committed to strengthening training protocols for maintenance supervisors and expanding internal reporting channels to ensure strict compliance with aviation Regulations.

AirPro News analysis

We observe that while the immediate infractions were committed by individual mechanics, the transport ministry’s advisory squarely targets ANA’s corporate entity. This regulatory approach underscores a systemic issue within the airline’s safety culture and middle-management oversight. The most critical factor driving the severe executive penalties is the “double strike” nature of the violations, the 2025 falsifications took place while the company was actively supposed to be reforming its maintenance culture following the 2024 Fukushima incident. Against a backdrop of heightened global scrutiny regarding aviation maintenance standards, ANA faces a steep climb to reassure both regulators and the flying public that its internal safety mechanisms are robust.
