Now Come ON!! You and I BOTH know Line pilots are NOT going to test fly anyrhing!!
You've NEVER assisted Maintenence in troubleshooting before and you're NOT going up to test airplanes coming out of maintenence or help Maintenence nail down problems or fly gear down ferries or test flights for horizontal stabilizer trim motor changes nor double engine changes. So WHY don't we quit the blather? Because I'll bet $50.00 the FIRST time I offer it? The FODM will fall over DEAD! You'd Never get the chance to even TRY! If you can refuse an airplane being ferried for lightning strike repairs with NO restrictions?? Are you Kidding me?
