No Checklist For This
I was flying a 2002-model A36 Bonanza (yeah, with me its always a Bonanza) home to Wichita from Thanksgiving in Ohio with my wife and our son aboard. Somewhere over Indiana, the Bonanzas attitude indicator (AI) began to tumble. The failure announced itself slowly, but very soon the instrument was pitching up and down in very distracting oscillations. It then displayed a range of indications-from off-scale nose-up pitch excursions to slightly below 20 degrees nose-down-in a roughly two-second cycle, while indicating bank angles between wings-level and about 10 degrees left.
