KL1789 - Incident: KLM Cityhopper E190 at Amsterdam on Jun 4th 2026

A KLM Cityhopper Embraer ERJ-190, registration PH-EZG performing flight KL-1789 from Amsterdam (Netherlands) to Hanover (Germany), was climbing out of Amsterdam's runway 24 when the crew stopped the climb at FL175 reporting an aft door unlocked message. The crew subsequently requested to descend to FL100 advising they had pressurization problems. The crew later advised it probably was just an indication, however, according to the checklists they had to divert to the nearest possible airport. The aircraft landed safely on Amsterdam's runway 22 about 30 minutes after departure.
