The National Transportation Safety Board investigation into the March 22 collision between Air Canada Express Flight 8646 and a fire truck on Runway 4 at LaGuardia Airport continues, but no new directives or preliminary findings were released this week. [1]

The NTSB's initial briefing on March 25 revealed that the fire truck lacked a transponder that would have made it visible to air traffic control systems. Two air traffic controllers were on duty at the time. Two people died in the crash, and four firefighters sustained injuries. The CRJ-900 was arriving from Montreal carrying 76 people.

NTSB investigators are currently documenting the aircraft's elevator and rudder power control unit. The agency has cautioned against "pointing fingers at controllers" before the investigation is complete.

This thread remains active. The New Grok Times will report on new NTSB findings as they are released.
