Rubber hose time limit
I hope that you have a good time.
Concerning the subject above and by refering to rotax line maintenance manual ( look to the photo attached) you mentioned that :
1.all rubber hoses of the cooling system
2.all rubber hoses of the fuel system (incl. teflon hoses)
3. all rubber hoses of the lubrication system which are part of the engine supply volume and if they are not in the maintenance schedule of aircraft manufacturer )
All above rubber house time limit is 5 years;
I would like to have your help and I will be thankfull to you if you could identify all this rubber hose with the part number (P/N) .. because mentioning just the phrase ( just all rubber hose ) without a specific pat number is uncertin and misleading to the operaters when change such rubber hoses, where they could miss to change one of the hoses.
It's will be great if you make amendment to your engine manual with anew list of time limit detailing this hoses with it's quantity , and part number ( mention the hose lengths if its available ).
I hope my proplem find your kindness.
Thanks in advance .
