B738 - G/A after 'gear indication problem'
Hi folks,
No 'near death experience', no school barely missed, just an operational inquiry :-)
Couple of weeks ago I was flying as pax. On approach to CGN, ~15 sec after the gear was lowered, a G/A was made. Gear/flaps were retracted normally. A minute or so later, captain's PA mentioned there was a gear indication problem and we'd hold to troubleshoot the issue. 10 mins later, another PA that the problem was cleared and we would return to land. During this troubleshooting process, no attempt to lower the gear was made.
Second approach and landing were uneventful.
Now my question: what could this have been? There are 2 pairs of gear indicator lights on the NG (next to the lever, on the aft overhead) so if it would have been just a green light not lighting up, the second indicator should have showed this, no? Or is this optional equipment (EI registered a/c)?
If there was a genuine concern the gear was not down/locked, surely an attempt to lower the gear during the troubleshooting process would have been made?
Not second guessing the crew, it was all handled well and calmly - just trying to understand the situation.
Thanks
Mark
