Four years after China Eastern Flight MU5735 crash, CAAC offers no explanation

For the second consecutive year China’s Civil Aviation Administration has not released an update into the crash of China Eastern Flight MU5735, allowing the fourth anniversary to pass without an explanation for why the aircraft nosedived from cruise instead of completing its descent to Guangzhou.

Briefing

What Hype is tracking

The CAAC has not published an annual update for a second straight year; the fourth anniversary passed without an official cause for MU5735's high‑speed descent from cruise, leaving victims' relatives and operators without technical findings needed for risk mitigation.
Without a public final report or interim safety recommendations, airlines and regulators lack actionable guidance to address potential systemic issues that could affect fleet operations or training standards.
The CAAC's silence comes amid other active probes and transparency questions in the region, including a Hong Kong tail‑strike inquiry and other recent accident investigations (see US turboprop crash probe and the missile‑fragment inquiry).
