Probably depends if they make the reporting penalty-free. If pilots have to report and then they end up with a mark on their record, companies will do what happens often here when problems occur--try to sweep it under the rug and hope it dissapears.
BTW (The media is now reporting that two JAL planes had reversers were locked and did not deploy on landing --one today, one last July). No end in sight for JAL's woes. . .
