The Yemenia Air flight that crashed near Moroni wasn’t built in the United States. It had no Americans on board, and no part of the flight was through U.S. airspace. The aircraft, however, was leased to Yemenia Air by a Los Angeles company, International Lease Finance Corporation, or “ILFC.” Could the Yemenia Air families successfully bring a lawsuit against ILFC in the U.S.? Perhaps, but only if they could prove all of the following:

1. That Yemenia Air Was Not Competent to Operate the Aircraft. The European Union banned the accident aircraft from entering EU airspace in 2007 after inspecting the aircraft and finding a long list of technical discrepancies. The EU is now considering banning the airline from operating any of its aircraft in EU airspace. The reason? The airline does not seem capable of operating safely. Apparently, Yemenia lacks the technical expertise, the resources, or the inspectors to make sure minimum safety standards are met. From what we know about Yemenia Air thus far, the families should have little difficulty proving that the airline was not competent to safely operate ILFC’s aircraft.

2. That ILFC Knew the Airline Was Not Competent. A lessor can be held accountable to those injured by a lessee airline’s incompetence if, when it entrusted the aircraft to the lessee airline, the lessor knew the airline was not competent to operate the aircraft safely. The legal theory is called “negligent entrustment.” Yemenia Air has a terrible reputation and the families would have a good chance of proving that the leasing company knew it. Red flags certainly would have been raised for ILFC at least by 2007, when it learned that the EU had banned its aircraft from EU airspace.

3. That the Federal Law Immunizing Lessors from Liability for the Negligence of their Lessees Does Not Apply. A federal statute, USC section 44112, states that one who leases an aircraft is not liable when the lessor has an accident. But that statute was designed to protect the lessor from “automatic” liability that might arise in some states simply because the leasing company owns the aircraft. It doesn’t protect a lessor from liability for its own wrongful conduct when, for example, it knowingly entrusts an aircraft to an airline that can’t operate it safely.

4. That it is More “Convenient” for ILFC to Litigate in the US Than in Yemen. The legal doctrine of forum non conveniens allows a US court to transfer a case to a foreign country if it believes that, all things considered, it would be more convenient for the parties. And a court in California did exactly that in the Flash Air case, which involved ILFC and a 2004 crash off the coast of Egypt. In the Flash Air case, the court transferred the case overseas because, among other reasons, it decided that the best evidence concerning the cause of the crash was overseas, and that evidence would be difficult to bring here.  That’s the same situation in this case. So overcoming ILFC’s “forum non conveniens” argument would be the families’ biggest challenge. There is, however, one significant difference between this case and the Flash Air case. This case would be all about ILFC’s “negligent entrustment” of the aircraft.  So in this case, the most important evidence concerns what ILFC knew about the airline’s level of competence. That evidence is most likely here, not overseas.
