When choosing a provider to repair your engine sling, several factors should be taken into account. All options should be considered to ensure you are choosing the best possible provider for you and your engine sling repair needs. A brief comparison between the engine sling manufacturer, a calibration lab or an on-site aviation technician should be completed when choosing an engine sling provider. This helps to weigh out the pros and cons of each type of provider. When looking at all three provider options, it is essential to consider cost, shipping, downtime and the technical competence of the provider.


If you choose to go with the manufacturer of an engine sling, you can always guarantee technical competence of the personnel working within the laboratory. The technicians that work for the engine sling’s manufacturing company will possess knowledge and skill on how to repair common damages to their products. Although choosing a manufacturer for your engine sling repair will most likely ensure the accuracy of the sling once it is returned, it is also the most expensive option and includes the largest amount of downtime. Manufacturer costs for any aviation repairs are known to be almost 30% more than those of a third-party provider. This cost percentage doesn’t even include the price for shipping.

Depending on the distance between you and the engine sling’s manufacturer, shipping prices could range anywhere from $500 to $2,000. Distance also plays a role in the amount of downtime associated with engine sling repair. Long distance can lead to long downtimes, which in turn can heavily affect your company’s revenue. Chance are, you will also most likely have to pay to send the engine sling to another lab, after repairs, for recalibration and load testing, which again could cost a significant amount of money and extend the amount of downtime.


If you choose to go with an accredited calibration lab for your engine sling repair, you can get repair and recalibration of your engine sling completed all at one time. This is a major benefit of choosing this option because extra money will not need to be spent to send an engine to multiply locations and downtime will also be decreased because a calibration lab can kill two birds with one stone. Also, a calibration lab will cost you 20-30% less than what an engine sling manufacturer would.

When choosing an accredited calibration lab, you are ensuring accuracy of your engine sling after it has been repaired and recalibrated. This is due to accredited calibration labs having personnel who are considered technically competent to the highest degree.


Choosing an on-site aviation technician to perform engine sling repair is, more times than not, the most cost effective option. By hiring an on-site technician, you could possibly save yourself thousands of dollars and a large sum of downtime. Another benefit of choosing this option an on-site technician for engine sling repair is, most on-site technicians come from calibration labs, therefore repairs and re-calibration can be completed right at the location your engine sling is already sitting at.

Engine slings aren’t all that repaired, your aircraft jacks need maintenance and repair too.
Here’s how to find the right provider for both.
