Industry: Aerospace Engineering & Engine Manufacturing (B2B/B2G)
Jurisdiction: Germany
Primary Regulator: LBA & EASA (Strictly for Aviation Safety & Airworthiness)
Important Safety Warning: Beware of fake customer service numbers on search engines. Only use official channels. Scammers frequently target aerospace supply chains with “invoice redirection” phishing emails (Business Email Compromise), claiming MTU’s banking details have changed. MTU Aero Engines procurement staff will never demand you pay an invoice to a new, unverified bank account via a generic email link.
Level 1: Customer Support (Kundenservice)
- How to complain:
- For Passengers (Flight Disruptions): Stop! If your commercial flight was delayed or canceled due to technical engine issues, you must file your compensation claim directly with the airline under EU Regulation 261/2004. MTU has no direct legal liability to individual passengers.
- For B2B Suppliers & Partners: Contact the MTU central corporate switchboard at 089 / 1489 0 or email info@mtu.de. For specific procurement or maintenance portal issues, contact your dedicated MTU supply chain manager.
- Source Verification: Impressum - MTU Aero Engines
- Availability: The central corporate hotline operates Monday to Friday during standard business hours (CET).
- Timeline: B2B commercial disputes and supply chain issues are dictated by complex international aviation contracts and SLAs, not standard consumer timelines.
Level 2: Formal Written Complaint & Mahnung
- Who to contact: Formally escalate a direct commercial or supplier dispute by sending a registered letter with return receipt (Einschreiben mit Rückschein) to their legally registered headquarters. Address it to the Management Board, MTU Aero Engines AG, Dachauer Straße 665, 80995 München, Germany. (Do not use house number 667).
- Source Verification: Impressum - MTU Aero Engines
- Timeline: A legally binding deadline of 14 days (set via your Mahnung) provides the company a strict timeframe to resolve a standard financial dispute before they legally default (in Verzug geraten).
Level 3: Regulatory Authority / ADR
- Authority: The correct escalation path depends entirely on the nature of your report:
- Commercial/Consumer Disputes: MTU Aero Engines AG explicitly refuses to participate in voluntary consumer arbitration boards like the Universalschlichtungsstelle.
- Aviation Safety/Whistleblowers: If you are an industry professional reporting severe, systemic airworthiness defects, safety violations, or unapproved parts (SUPs), you must report this directly to the Luftfahrt-Bundesamt (LBA) or the European Union Aviation Safety Agency (EASA).
- Source Verification: LBA - Meldung von Ereignissen
Level 4: Legal Action
- Pre-Litigation: Before initiating formal court proceedings, commercial entities should seek case-specific legal assistance from a specialized corporate aviation or contract lawyer.
- Court/Arbitration: Critical Legal Trap: Private consumers attempting to sue MTU directly for a ruined vacation due to an engine failure will have their lawsuit dismissed by German civil courts due to a lack of privity of contract (Vertragsrelativität). Consumers must sue their airline. Commercial B2B disputes against MTU are typically handled via private commercial arbitration or the competent Regional Court (Landgericht München).
