France's Bureau d'Enquêtes et d'Analyses published its final report on 13 March 2016, confirming that Lubitz intentionally activated the descent and held it until impact. The report found no mechanical failure, weather event, or external actor.

The CVR captured Captain Sondenheimer entering emergency codes, using the intercom, and physically striking the reinforced cockpit door — all while Lubitz's only audible sounds were normal, controlled breathing. The record is unambiguous regarding intent.

Investigators confirmed Lubitz manually selected 100 feet as the target altitude — a deliberate selection far below the approach minimums for any destination and inconsistent with any plausible accidental or medical-incapacitation scenario.

German prosecutors found torn-up sick notes — including one declaring Lubitz unfit to fly on the day of the crash — at his Düsseldorf apartment, alongside records of psychiatric treatment and internet searches about suicide methods and cockpit door locks.

Medical records recovered by investigators documented Lubitz's treatment for severe depressive episodes beginning in 2008, including a period that had temporarily suspended his flight training. He did not disclose the full history to aviation medical examiners.

Lubitz's treating psychiatrist had issued a certificate declaring him medically unfit to fly in the days before the crash. Lubitz concealed this by not submitting the certificate to Germanwings. The disclosure gap was a central finding of the post-accident regulatory review.

European Aviation Safety Agency and Germany's Luftfahrt-Bundesamt strengthened pilot medical disclosure requirements after the crash, requiring pilots to consent to disclosure of disqualifying conditions directly to AMEs — addressing the regulatory gap Lubitz exploited.

Many European airlines adopted a rule requiring a second crew member in the cockpit whenever one pilot left within days of the crash. Several carriers rescinded this rule between 2015 and 2017 after cabin crew unions raised concerns about crew safety implications, illustrating the difficulty of simple regulatory fixes.

The EASA and German LBA operated under strict EU privacy frameworks that legally constrained cross-border sharing of pilot mental-health records. Lubitz's prior psychiatric flags were partially documented but German aviation medicine law prohibited full disclosure to employers without consent. Framing this structural legal barrier as deliberate institutional concealment overstates coordinated intent — the system had documented procedural gaps that post-crash reforms addressed, rather than evidence of a cover-up designed to hide a known dangerous pilot.

The BEA accident investigation systematically excluded mechanical failure, hypoxia, and third-party incapacitation scenarios using flight data recorder inputs, CVR audio, and forensic toxicology. Describing the outcome as a conspiracy overstates ambiguity: the evidence trail is unusually complete for an aviation accident. The tragedy reflects regulatory failure around mental-health disclosure in a privacy-rights context, not a coordinated institutional conspiracy to suppress knowledge of a predictably homicidal pilot.

Lufthansa's medical department had records of Lubitz's 2009 depressive episode and treatment, but German data-protection law and pilot medical confidentiality rules restricted how this information could be shared with operational safety departments. The BEA investigation found no evidence of deliberate suppression by Lufthansa management — rather, information flowed through separate, legally partitioned channels. The tragedy reflects a systemic privacy-versus-safety design failure, not a corporate cover-up of known imminent risk.

European aviation medical certification rules prior to 2015 balanced pilot privacy rights against safety disclosure requirements — a tension present across most liberal democracies. Andreas Lubitz's treating physicians operated under German medical confidentiality law, which limited disclosure to aviation authorities absent specific statutory override. The BEA accident report identified this as a systemic gap requiring reform, not evidence of deliberate concealment. Post-accident EASA reforms to multi-crew principles and medical disclosure reflect the system correcting identified deficiencies.
