I am looking for two MM19 indices from the cost indices for the manufacture of aircraft and spacecraft - SIC 2007 Section 4. Namely, earning and national insurance and purchases of materials and fuels.
I am interested in the ones from 2010 until present.

Thank you for your enquiry,
Due to methodology changes within the Producer Price Index (PPI) we no longer publish the MM19 dataset. The changes made to the PPI include:
- The move from net to gross
- The removal of duty
- The implementation of chain-linking
Please see the following link to the last publication of the MM19 (July 2020 data): MM19 dataset cessation – replacement indices. The recommended index replacements are included within the spreadsheet, along with the formulas needed to convert some of the indices. Within the tables there is a column with a formula that manually calculates combined costs, this will allow you to calculate this yourself going forward with the new indices, but please be aware that these weights will no longer be updated.
We would advise reading the following article before using the indices: Producer Price Indices methods changes. The article provides details of the recently implemented methodological changes in the PPI (mentioned above) so you can understand how these changes impact you.
