Correction
In rule document 2012-13828 appearing on pages 36341-36386 in the issue of Monday, June 18, 2012, make the following corrections:
§ 87.23 [Corrected]
1. On page 36382, in § 87.23, the table titled "Table 3 to § 87.23-Tier 6 NO X Standards for New Subsonic Turbofan or Turbojet Engines with Rated Output Above 26.7 kN" should read as set forth below:
| If the rated pressure ratio is- | and the rated output (in kN) is- | The NO X emission standard (in g/kN rated output) is- |
|---|---|---|
| rPR = 30 | 26.7 < rO = 89 | 38.5486 + 1.6823·rPR - 0.2453·rO - 0.00308·rPR·rO |
| rO > 89 | 16.72 + 1.4080·rPR | |
| 30 < rPR < 82.6 | 26.7 < rO = 89 | 46.1600 + 1.4286·rPR - 0.5303·rO + 0.00642·rPR·rO |
| rO > 89 | -1.04 + 2.0·rPR | |
| rPR = 82.6 | all | 32 + 1.6·rPR |
2. On page 36383, in § 87.23, the table titled "Table 4 to § 87.23-Tier 8 NO X Standards for New Subsonic Turbofan or Turbojet Engines with Rated Output Above 26.7 kN" should read as set forth below:
| If the rated pressure ratio is- | and the rated output (in kN) is- | The NO X emission standard (in g/kN rated output) is- |
|---|---|---|
| rPR = 30 | 26.7 < rO = 89 | 40.052 + 1.5681·rPR - 0.3615·rO - 0.0018·rPR·rO |
| rO > 89 | 7.88 + 1.4080·rPR | |
| 30 < rPR < 104.7 | 26.7 < rO = 89 | 41.9435 + 1.505·rPR - 0.5823·rO + 0.005562·rPR·rO |
| rO > 89 | -9.88 + 2.0·rPR | |
| rPR = 104.7 | all | 32 + 1.6·rPR |
