Ah, no. He is entitled to say that he thinks that the failure of the battery is
the proximate cause of the ELT going off. He is not entitled to say that this
is a design flaw unless he could have done the original design himself...just
like you cannot say that the BD-5 has an inherent aerodynamic design flaw
because a few of them have turned into smoking holes. UNLESS you are capable of
doing the design analysis yourself, in which case I will respect your judgement.
In ANY case, you would be irresponsible to make such a statement until you had
contacted the original designer and discussed the matter with him/her.

-And what credentials do you possess to make this determination?
