Errors in forms Untilnow,whenaDAMEforgottoentersomedataontheformwewouldsendbackaletteraskingforthattobecorrectedandsentback.Werecentlyhadthise-mailconversationwitha DAME.

“Looks like the f*** up is mine. I obviously omitted to put on the form your **** dose, assuming that the specialist’s report was adequate. Call me tomorrow and remind me to fax the details to those bureaucrats at CASA. I can only apologise. I didn’t think CASA were that petty”. (senttoCASAbymistake)

IwrotetotheDAMEsaying,“ ….. I am happy to discuss how we can make the system more friendly. I am very conscious that our DAMEs are a very important resource, and I would certainly like us all to operate from the same song sheet. I have had recent feedback about our becoming more human, which is good, but I need to explore the specific issue you raise, to see whether there is any legal room to move. If you have any other issues, I am always open to listening. I can only promise that I will engage, not that I will necessarily agree, but I am sure that is a step in the right direction. So if you have suggestions, do drop me a line, and we can then argue about them!”

TheresponseIgotis“I’d like to suggest that if any further information is needed (ie, that’s been accidentally missed) from a DAME form, that the DAME receives either a fax or a phone call, requesting the information. This information could then be given verbally and recorded by you - for legal purposes. The information is then faxed to you by the DAME - who stamps the fax with the DAME stamp. This should satisfy all normal legal requirements and would be just as secure as any other method. (Lawyers use faxes for multi million dollar contracts, Telstra ad banks accept verbal authorizations, having established that the person they are speaking to is the authorized account holder) CASA won’t accept a verbal confirmation of a pulse rate! More than that, you send a letter to the doctor and patient, that is almost like a schoolboy’s parents receiving notification that the pupil has been a naughty boy. Things have to be right, because aviation safety is no small matter but surely, the present system is too authoritarian, too bureaucratic and too inefficient in certain instances.”

Formysins,IamcurrentlyundergoinganMBAtrainingprogramme.Doingthiscourse,oneofthethingswhichwelearnedisthatwhensomeonecomplains,thatisthemomentoftruth.Becausehowthatcomplaintisdealt

with,says,muchlouderthanwords,howwethinkaboutthepersonwhomadethecomplaint.

So,withimmediateeffect(thisone’snotwaitinguntilthe31stJanuary)ifsomebodydetectsanerrorontheform,wewillringupandleaveamessagewiththeDAME’sofficeexplainingwhatisneeded.Wewouldthenrequestafaxedcorrection,whichwewillscanonthefile.(Obviously,ifwedonotreceiveafaxedcorrection,wewillnotproceedfurther).Thatway,thedictatesoflegalcorrectness,andthatofconveniencewillbemet.
