To give you an idea of the running costs of MTI, I am listing some of the costs to be expected:
Hangarage / Landing Fees
Unfortunately I can’t give you a figure for where you are based, so ask at your field. However if this is in Germany or if you intend on landing in Germany. MTI does have a noise certificate. This is not normally the case for foreign homebuilts but I had noise testing carried out and this means landing fees are very moderate – I typically pay between €6 – €13 depending on the airfield.
Insurance
Insurance costs around €800 for general third party and slightly less than 2% of hull value for CSL, hence total insurance costs are around €3600 p.a. The insurer we use provides coverage for all pilots, no need to name pilots.
Maintenance
Maintenance
This can vary depending on who does the maintenance. Maintenance is once a year or every 100 hours, whichever comes first. If you have the maintenance carried out by GoGetAir in Slovenia, their current price list shows airframe annual to be around €850 with engine maintenance approximately the same. However it should be noted that if you use leaded fuel, the inspection interval for the engine is reduced to every 50 hours. However this doesn’t mean you can’t have your local maintenance shop carry out the work – we’ve done this, not a problem.
Concerning the permit to fly, this needs to be renewed once a year although we are hearing news that there are discussions under way to extend this to once every two years. For the permit, the Slovenian CAA inspector needs to see the plane and the documents – hence we typically combine a trip to Slovenia with the permit prolongation – you can prepare the paperwork for this yourself but I prefer to allow GoGetAir to handle it which costs €550 but ensures when I turn up late afternoon on the day before permit prolongation that, by the close of play the next day, the permit has been renewed and the annual service on airframe and engine has been completed.
Fuel & Oil
The 912iS engine in MTI is very economical, it also doesn’t use any oil during inspections although we always have a quart with us, “just in case”. Typically our flights are around 1 hour in duration although we have flown 3 – 4 hours in a go. The average fuel burn in cruise is around 17 litres of Super 95 per hour but this can be significantly lower, the higher you go. If I am flying more than 1 hour, I will typically climb to FL 065 or 085 and burn between 14 and 15 litres per hour for Super 95.
Miscellaneous expenses
Other expenses with MTI have been relatively low with no serious issues during the 240+ hours we have operated her. I subscribe to EasyVFR and update the maps on the SkyView HDX on a monthly basis – this ensures my charts are always up to date. This costs around €140 / annum and includes the use of EasyVFR 4 for the phone.
Radio permit is due once a year and this costs around €49.
