Do commercial pilots undergo specific training for dealing with horizontal stabilizer/jackscrew failures such as the one that took place in the case of Alaska Flight 261?

I was watching a YouTube video about Alaska Airlines Flight 261 earlier, and it made me curious. I understand that failures like this are extremely rare today because of stricter maintenance and inspection procedures, so I'm not worried about it happening.
Detailed analysis

Alaska Airlines Flight 261 remains one of the most studied accidents in commercial aviation history, and the question of whether pilots specifically train for jackscrew or horizontal stabilizer failures touches on a critical distinction in how the industry approaches simulator training: the difference between training for specific failure modes versus training for the resulting flight characteristics. The January 2000 accident was ultimately traced to inadequate lubrication of the horizontal stabilizer trim system's jackscrew assembly, which led to catastrophic thread stripping on the acme nut and allowed the stabilizer to move to an extreme trailing-edge-up position, rendering the aircraft essentially uncontrollable in pitch. The NTSB's investigation found that Alaska Airlines had extended lubrication intervals beyond manufacturer recommendations, a maintenance-program failure rather than a design flaw in isolation, though it also exposed the lack of a fail-safe secondary load path in the MD-80's stabilizer trim design.

For working pilots, the honest answer is that no airline trains specifically for "jackscrew failure" as a named scenario in recurrent simulator sessions, because it is not a checklist item or a QRH procedure in the way an engine fire or hydraulic failure is. What pilots do train extensively for is runaway stabilizer trim, jammed or split elevator control, and unusual attitude recovery at various speeds and configurations, all of which share overlapping symptoms with what the Alaska 261 crew experienced. Type-specific differences bureau, if the horizontal stabilizer physically separates or the jackscrew fails catastrophically, there is effectively no certified recovery procedure, because the aircraft's aerodynamic controllability envelope has been fundamentally violated. The CVR transcript from Flight 261 is haunting precisely because the crew was improvising, using asymmetric thrust and full nose-down elevator input to briefly regain a semblance of controlled flight before the stabilizer fully departed its jackscrew limits, an outcome that no simulator training package anticipates because it falls outside the certified flight envelope entirely.

This distinction matters enormously for how operators and regulators think about training resources. Simulator curricula, governed by FAA Advisory Circular 120-109 and similar guidance on Extended Envelope Training (EET), focus on statistically probable failure modes and loss-of-control scenarios drawn from accident data trends, things like stall recovery, upset prevention, and asymmetric thrust management following the 2009 Colgan Air crash. A jackscrew failure of the type seen on Flight 261 is now considered a legacy risk largely mitigated at the source through the airworthiness directives that followed the accident, including revised lubrication intervals, end-play checks, and eventual redesign requirements for stabilizer trim systems on MD-80/DC-9 derivative aircraft. Rather than building simulator scenarios around a failure mode now considered engineered out of existence, the industry channeled its energy into maintenance-program reform and design fail-safes, which is arguably a more effective use of resources than training pilots to "recover" from an essentially unrecoverable structural failure.

The broader lesson for pilots and aviation professionals is that catastrophic structural failures like Alaska 261 tend to drive systemic change through maintenance and design rather than through crew procedure alone, unlike, say, engine failures or electrical faults where a trained checklist response genuinely changes outcomes. This is a pattern seen repeatedly across aviation safety history, from the Aloha Airlines fuselage failure driving corrosion-inspection programs to the more recent 737 MAX MCAS crashes driving both software fixes and expanded manual trim training. For today's pilots, the practical takeaway is that recurrent training on stabilizer trim runaways, electric and manual trim wheel operation, and unusual attitude recovery remains directly relevant, since those skills form the closest analog available, even though no simulator can faithfully replicate a total loss of pitch authority from a physically failed jackscrew. The crew of Flight 261 did what any well-trained crew would do when facing symptoms resembling a trim runaway, and their efforts, while ultimately unsuccessful, directly influenced how thoroughly modern maintenance programs now scrutinize flight-critical mechanical systems that have no redundant load path.
